-
-Create a DNS reply.
-
-The reply will be based on an existing query message `msg`.
-The query body will be appended to the output buffer.
-"reply + recursion allowed" will be added to the message flags and
-message's num_answers will be set to 0.
-
-Answer records can be appended with `mg_dns_send_reply` or by lower
-level function defined in the DNS API.
-
-In order to send the reply use `mg_dns_send_reply`.
-It's possible to use a connection's send buffer as reply buffers,
-and it will work for both UDP and TCP connections.
-
-Example:
-
-```c
-reply = mg_dns_create_reply(&nc->send_mbuf, msg);
-for (i = 0; i < msg->num_questions; i++) {
- rr = &msg->questions[i];
- if (rr->rtype == MG_DNS_A_RECORD) {
- mg_dns_reply_record(&reply, rr, 3600, &dummy_ip_addr, 4);
- }
-}
-mg_dns_send_reply(nc, &reply);

- This event is sent before body is parsed. After this user
- should expect a sequence of MG_EV_HTTP_PART_BEGIN/DATA/END requests.
- This is also the last time when headers and other request fields are
- accessible.
-- MG_EV_HTTP_REPLY: HTTP reply has arrived. Parsed HTTP reply is passed as
- `struct http_message` through the handler's `void *ev_data` pointer.
-- MG_EV_HTTP_CHUNK: HTTP chunked-encoding chunk has arrived.
- Parsed HTTP reply is passed as `struct http_message` through the
- handler's `void *ev_data` pointer. `http_message::body` would contain
- incomplete, reassembled HTTP body.
- It will grow with every new chunk arrived, and
- potentially can consume a lot of memory. An event handler may process
- the body as chunks are coming, and signal Mongoose to delete processed
- body by setting `MG_F_DELETE_CHUNK` in `mg_connection::flags`. When
- the last zero chunk is received,
- Mongoose sends `MG_EV_HTTP_REPLY` event with
- full reassembled body (if handler did not signal to delete chunks) or
- with empty body (if handler did signal to delete chunks).
-- MG_EV_WEBSOCKET_HANDSHAKE_REQUEST: server has received websocket handshake
- request. `ev_data` contains parsed HTTP request.
-- MG_EV_WEBSOCKET_HANDSHAKE_DONE: server has completed Websocket handshake.
- `ev_data` is `NULL`.
-- MG_EV_WEBSOCKET_FRAME: new websocket frame has arrived. `ev_data` is
- `struct websocket_message *`
-- MG_EV_HTTP_PART_BEGIN: new part of multipart message is started,
- extra parameters are passed in mg_http_multipart_part
-- MG_EV_HTTP_PART_DATA: new portion of data from multiparted message
- no additional headers are available, only data and data size
-- MG_EV_HTTP_PART_END: final boundary received, analogue to maybe used to
- find the end of packet
- Note: Mongoose should be compiled with MG_ENABLE_HTTP_STREAMING_MULTIPART
- to enable MG_EV_HTTP_MULTIPART_REQUEST, MG_EV_HTTP_REQUEST_END,

- void mg_mqtt_broker(struct mg_connection *brk, int ev, void *data);
----
-
-Process a MQTT broker message.
-
-Listening connection expects a pointer to an initialized `mg_mqtt_broker`
-structure in the `user_data` field.
-
-Basic usage:
-
-```c
-mg_mqtt_broker_init(&brk, NULL);
-
-if ((nc = mg_bind(&mgr, address, mg_mqtt_broker)) == NULL) {
- // fail;
-}
-nc->user_data = &brk;
-```
-
-New incoming connections will receive a `mg_mqtt_session` structure
-in the connection `user_data`. The original `user_data` will be stored
-in the `user_data` field of the session structure. This allows the user
-handler to store user data before `mg_mqtt_broker` creates the session.
-
-Since only the MG_EV_ACCEPT message is processed by the listening socket,
-for most events the `user_data` will thus point to a `mg_mqtt_session`.

-
-`remote_ip` - an IPv4 address to check, in host byte order
-`acl` - a comma separated list of IP subnets: `x.x.x.x/x` or `x.x.x.x`.
-Each subnet is
-prepended by either a - or a + sign. A plus sign means allow, where a
-minus sign means deny. If a subnet mask is omitted, such as `-1.2.3.4`,
-this means to deny only that single IP address.
-Subnet masks may vary from 0 to 32, inclusive. The default setting
-is to allow all accesses. On each request the full list is traversed,
-and the last match wins. Example:
-
-`-0.0.0.0/0,+192.168/16` - deny all acccesses, only allow 192.168/16 subnet
-
-To learn more about subnet masks, see the
-link:https://en.wikipedia.org/wiki/Subnetwork[Wikipedia page on Subnetwork]
-
-Return -1 if ACL is malformed, 0 if address is disallowed, 1 if allowed.

-`address` format is `[PROTO://]HOST:PORT`. `PROTO` could be `tcp` or `udp`.
-`HOST` could be an IP address,
-IPv6 address (if Mongoose is compiled with `-DMG_ENABLE_IPV6`), or a host

-of valid addresses: `google.com:80`, `udp://1.2.3.4:53`, `10.0.0.1:443`,
-`[::1]:80`
-
-See the `mg_connect_opts` structure for a description of the optional

-
-Returns a new outbound connection, or `NULL` on error.
-
-NOTE: Connection remains owned by the manager, do not free().
-
-NOTE: To enable IPv6 addresses, `-DMG_ENABLE_IPV6` should be specified
-in the compilation flags.
-
-NOTE: New connection will receive `MG_EV_CONNECT` as it's first event
-which will report connect success status.
-If asynchronous resolution fail, or `connect()` syscall fail for whatever
-reason (e.g. with `ECONNREFUSED` or `ENETUNREACH`), then `MG_EV_CONNECT`
-event report failure. Code example below:
-
-```c
-static void ev_handler(struct mg_connection *nc, int ev, void *ev_data) {
- int connect_status;
-
- switch (ev) {
- case MG_EV_CONNECT:

+
+== Design Concept
+
+Mongoose is a multi-protocol networking library that implements non-blocking,
+asyncronous IO and provides event-based API. It has three basic data structures:
+
+- link:#_struct_mg_mgr[`struct mg_mgr`] is an event manager
+ that holds all active connections
+- link:#_struct_mg_connection[`struct mg_connection`] describes a connection
+- link:#_struct_mbuf[`struct mbuf`] describes data buffer
+ (received or sent data)
+
+Connections could be either *listening*, *outbound* or *inbound*.
+Outbound connections are created by link:#_mg_connect[`mg_connect()`] call.
+Listening connections are created by link:#_mg_bind[`mg_bind()`] call.
+Inbound connections are those accepted by a listening connection.
+Each connection is described by
+link:#_struct_mg_connection[`struct mg_connection`] structure, which has
+a number of fields like socket, event handler function, send/receive buffer,
+flags, et cetera.
+
+Mongoose usage pattern is to declare and initialize event manager, create
+connections and create an event loop by calling
+link:#_mg_mgr_poll[`mg_mgr_poll()`] in a loop.
+link:#_mg_mgr_poll[`mg_mgr_poll()`] iterates over all sockets,
+accepts new connections, sends and receives data, closes connections,
+and calls event handler functions for the respective events.
+
+=== Memory buffers
+
+Each connection has send and receive buffer,
+link:#_struct_mg_connection[`struct mg_connection::send_mbuf`]
+and
+link:#_struct_mg_connection[`struct mg_connection::recv_mbuf`] respectively.
+When data arrives,
+Mongoose appends received data to the `recv_mbuf` and
+triggers `MG_EV_RECV` event. User may send data back by calling one of the
+output functions, like link:#_mg_send[`mg_send()`] or
+link:#_mg_printf[`mg_printf()`]. Output functions append data to the
+`send_mbuf`. When Mongoose
+successfully writes data to the socket, it discards data from
+link:#_struct_mg_connection[`mg_connection::send_mbuf`] and
+sends `MG_EV_SEND` event. When connection is closed, `MG_EV_CLOSE` event is sent.
+
+image::mongoose/mbuf.png[width="600",align="center"]
+
+=== Event handler function
+
+Each connection has an event handler function associated with it. That
+function must be implemented by user. Event handler is the key element of
+the Mongoose application, since it defines application's behavior. This is how
+an event handler function looks like:
+
+[source,c]
+----
+static void ev_handler(struct mg_connection *nc, int ev, void *ev_data) {
+ switch (ev) {
+ /* Event handler code that defines behavior of the connection */
+ ...
+ }
+}
+----
+
+struct mg_connection *nc::
+ Connection that has received an event.
+
+int ev::
+ Event number, defined in `mongoose.h`. For example, when data arrives
+ on inbound connection `ev` would be `MG_EV_RECV`.
+
+void *ev_data::
+ This pointer points to the event-specific data, and it has different
+ meaning for different events. For example, for `MG_EV_RECV` event,
+ `ev_data` is an `int *` pointer, pointing to the number of bytes received
+ from the remote peer and saved into the receive IO buffer. Exact meaning
+ of `ev_data` is described for each event. Protocol-specific events usually
+ have `ev_data` pointing to structures that hold protocol-specific information.
+
+NOTE: link:#_struct_mg_connection[`struct mg_connection`] has `void *user_data`
+which is a placeholder for a application-specific data. Mongoose does not use
+that pointer. Event handler can store any kind of information there.
+
+=== Events
+
+Mongoose accepts incoming connections, reads and writes data, and
+calls specified event handler for each connection when appropriate. Typical
+event sequence is this:
+
+- For outbound connection: `MG_EV_CONNECT` -> (`MG_EV_RECV`, `MG_EV_SEND`, `MG_EV_POLL` ...) -> `MG_EV_CLOSE`
+- For inbound connection: `MG_EV_ACCEPT` -> (`MG_EV_RECV`, `MG_EV_SEND`, `MG_EV_POLL` ...) -> `MG_EV_CLOSE`
+
+
+Below is a list
+of core events triggered by Mongoose (note that each protocol triggers
+protocol-specific events in addition to the core ones):
+
+MG_EV_ACCEPT:: sent when new server connection is accepted by a
+listening connection. `void *ev_data` is `union socket_address`
+of the remote peer.
+MG_EV_CONNECT:: sent when a new outbound connection created by
+link:#_mg_connect[`mg_connect()`]
+either failed or succeeded. `void *ev_data` is `int *success`.
+If `success` is 0, then connection has been established,
+otherwise it contains error code. See
+link:#_mg_connect_opt[`mg_connect_opt()`] function for code example.
+
+MG_EV_RECV:: New data is received and appended to the end of `recv_mbuf`.
+`void *ev_data` is `int *num_received_bytes`. Typically, event handler
+should check received data in `nc->recv_mbuf`,
+discard processed data by calling link:#_mbuf_remove[`mbuf_remove()`],
+set connection flags `nc->flags` if necessary
+(see link:#_struct_mg_connection[`struct mg_connection`]), and write
+data the remote peer by output functions like link:#_mg_send[`mg_send()`].
+
+WARNING: Mongoose uses `realloc()` to expand receive buffer.
+It is user's responsibility to discard processed
+data from the beginning of receive buffer, note the `mbuf_remove()`
+call in the example above.
+
+MG_EV_SEND:: Mongoose has written data to the remote peer and discarded
+written data from the
+link:#_struct_mg_connection[`mg_connection::send_mbuf`]. `void *ev_data`
+is `int *num_sent_bytes`.
+
+NOTE: Mongoose output functions only append
+data to the `mg_connection::send_mbuf`, they do not do any socket writes.
+An actual IO is done by link:#_mg_mgr_poll[`mg_mgr_poll()`]. `MG_EV_SEND` event
+is just a notification about an IO has been done.
+
+MG_EV_POLL:: Sent to all connections on each invocation of
+link:#_mg_mgr_poll[`mg_mgr_poll()`].
+This event could be used to do any housekeeping, for example check whether
+certain timeout has expired and close the connection, or send heartbeet
+message, et cetera.
+
+MG_EV_TIMER:: Sent to the connection if
+link:#_mg_set_timer[`mg_set_timer()`] was called.
+
+=== Connection flags
+
+Each connection has a `flags` bit field. Some flags are set by Mongoose, for
+example if a user creates an outbound UDP connection using `udp://1.2.3.4:5678`
+address, Mongoose is going to set `MG_F_UDP` flag for that connection. Other flags
+are meant to be set only by user event handler to tell Mongoose how to behave.
+Below is a list of connection flags that are meant to be set by event handlers:
+
+* `MG_F_FINISHED_SENDING_DATA` tells Mongoose that all data has been
+ appended to the `send_mbuf`. As soon as Mongoose sends it to the
+ socket, the connection will be closed.
+* `MG_F_BUFFER_BUT_DONT_SEND` tells Mongoose to append data to the
+ `send_mbuf` but hold on sending it, because the data will be modified
+ later and then will be sent by clearing `MG_F_BUFFER_BUT_DONT_SEND` flag.
+* `MG_F_CLOSE_IMMEDIATELY` tells Mongoose to close the connection
+ immediately, usually after some error
+* `MG_F_USER_1`, `MG_F_USER_2`, `MG_F_USER_3`, `MG_F_USER_4` could be
+ used by a developer to store application-specific state
+
+Flags below are set by Mongoose:
+
+* `MG_F_SSL_HANDSHAKE_DONE` SSL only, set when SSL handshake is done.
+* `MG_F_CONNECTING` set when connection is in connecting state after
+ `mg_connect()` call but connect did not finish yet.
+* `MG_F_LISTENING` set for all listening connections
+* `MG_F_UDP` set if connection is UDP
+* `MG_F_IS_WEBSOCKET` set if connection is a Websocket connection
+* `MG_F_WEBSOCKET_NO_DEFRAG` should be set by a user if user wants to switch
+ off automatic Websocket frame defragmentation

+==== mg_set_protocol_http_websocket()
+
+[source,c]
+----
+void mg_set_protocol_http_websocket(struct mg_connection *nc);
+----
+Attach built-in HTTP event handler to the given connection.
+User-defined event handler will receive following extra events:
+
+- MG_EV_HTTP_REQUEST: HTTP request has arrived. Parsed HTTP request
+ is passed as
+ `struct http_message` through the handler's `void *ev_data` pointer.
+- MG_EV_HTTP_MULTIPART_REQUEST: A multipart POST request has received.
+ This event is sent before body is parsed. After this user
+ should expect a sequence of MG_EV_HTTP_PART_BEGIN/DATA/END requests.
+ This is also the last time when headers and other request fields are
+ accessible.
+- MG_EV_HTTP_REPLY: HTTP reply has arrived. Parsed HTTP reply is passed as
+ `struct http_message` through the handler's `void *ev_data` pointer.
+- MG_EV_HTTP_CHUNK: HTTP chunked-encoding chunk has arrived.
+ Parsed HTTP reply is passed as `struct http_message` through the
+ handler's `void *ev_data` pointer. `http_message::body` would contain
+ incomplete, reassembled HTTP body.
+ It will grow with every new chunk arrived, and
+ potentially can consume a lot of memory. An event handler may process
+ the body as chunks are coming, and signal Mongoose to delete processed
+ body by setting `MG_F_DELETE_CHUNK` in `mg_connection::flags`. When
+ the last zero chunk is received,
+ Mongoose sends `MG_EV_HTTP_REPLY` event with
+ full reassembled body (if handler did not signal to delete chunks) or
+ with empty body (if handler did signal to delete chunks).
+- MG_EV_WEBSOCKET_HANDSHAKE_REQUEST: server has received websocket handshake
+ request. `ev_data` contains parsed HTTP request.
+- MG_EV_WEBSOCKET_HANDSHAKE_DONE: server has completed Websocket handshake.
+ `ev_data` is `NULL`.
+- MG_EV_WEBSOCKET_FRAME: new websocket frame has arrived. `ev_data` is
+ `struct websocket_message *`
+- MG_EV_HTTP_PART_BEGIN: new part of multipart message is started,
+ extra parameters are passed in mg_http_multipart_part
+- MG_EV_HTTP_PART_DATA: new portion of data from multiparted message
+ no additional headers are available, only data and data size
+- MG_EV_HTTP_PART_END: final boundary received, analogue to maybe used to
+ find the end of packet
+ Note: Mongoose should be compiled with MG_ENABLE_HTTP_STREAMING_MULTIPART
+ to enable MG_EV_HTTP_MULTIPART_REQUEST, MG_EV_HTTP_REQUEST_END,
+ MG_EV_HTTP_REQUEST_CANCEL, MG_EV_HTTP_PART_BEGIN, MG_EV_HTTP_PART_DATA,

+==== mg_send_websocket_handshake()
+
+[source,c]
+----
+void mg_send_websocket_handshake(struct mg_connection *nc, const char *uri,
+ const char *extra_headers);
+----
+Send websocket handshake to the server.
+
+`nc` must be a valid connection, connected to a server. `uri` is an URI
+to fetch, extra_headers` is extra HTTP headers to send or `NULL`.
+
+This function is intended to be used by websocket client.
+
+Note that the Host header is mandatory in HTTP/1.1 and must be
+included in `extra_headers`. `mg_send_websocket_handshake2` offers
+a better API for that.
+
+Deprecated in favour of `mg_send_websocket_handshake2`
+
+==== mg_send_websocket_handshake2()
+
+[source,c]
+----
+void mg_send_websocket_handshake2(struct mg_connection *nc, const char *path,
+ const char *host, const char *protocol,
+ const char *extra_headers);
+----
+Send websocket handshake to the server.
+
+`nc` must be a valid connection, connected to a server. `uri` is an URI
+to fetch, `host` goes into the `Host` header, `protocol` goes into the
+`Sec-WebSocket-Proto` header (NULL to omit), extra_headers` is extra HTTP
+headers to send or `NULL`.
+
+This function is intended to be used by websocket client.
+
+==== mg_connect_ws()
+
+[source,c]
+----
+struct mg_connection *mg_connect_ws(struct mg_mgr *mgr,
+ mg_event_handler_t event_handler,
+ const char *url, const char *protocol,
+ const char *extra_headers);
+----
+Helper function that creates an outbound WebSocket connection.
+
+`url` is a URL to connect to. It must be properly URL-encoded, e.g. have
+no spaces, etc. By default, `mg_connect_ws()` sends Connection and
+Host headers. `extra_headers` is an extra HTTP headers to send, e.g.
+`"User-Agent: my-app\r\n"`.
+If `protocol` is not NULL, then a `Sec-WebSocket-Protocol` header is sent.
+
+Examples:
+
+```c
+ nc1 = mg_connect_ws(mgr, ev_handler_1, "ws://echo.websocket.org", NULL,
+ NULL);
+ nc2 = mg_connect_ws(mgr, ev_handler_1, "wss://echo.websocket.org", NULL,
+ NULL);
+ nc3 = mg_connect_ws(mgr, ev_handler_1, "ws://api.cesanta.com",
+ "clubby.cesanta.com", NULL);
+```
+
+==== mg_connect_ws_opt()
+
+[source,c]
+----
+struct mg_connection *mg_connect_ws_opt(struct mg_mgr *mgr,
+ mg_event_handler_t ev_handler,
+ struct mg_connect_opts opts,
+ const char *url, const char *protocol,
+ const char *extra_headers);
+----
+Helper function that creates an outbound WebSocket connection
+
+Mostly identical to mg_connect_ws, but allows to provide extra parameters
+(for example, SSL parameters
+
+==== mg_send_websocket_frame()
+
+[source,c]
+----
+void mg_send_websocket_frame(struct mg_connection *nc, int op_and_flags,
+ const void *data, size_t data_len);
+----
+Send websocket frame to the remote end.
+
+`op_and_flags` specifies frame's type, one of:
+
+- WEBSOCKET_OP_CONTINUE
+- WEBSOCKET_OP_TEXT
+- WEBSOCKET_OP_BINARY
+- WEBSOCKET_OP_CLOSE
+- WEBSOCKET_OP_PING
+- WEBSOCKET_OP_PONG
+
+Orred with one of the flags:
+
+- WEBSOCKET_DONT_FIN: Don't set the FIN flag on the frame to be sent.
+
+`data` and `data_len` contain frame data.
+
+==== mg_send_websocket_framev()
+
+[source,c]
+----
+void mg_send_websocket_framev(struct mg_connection *nc, int op_and_flags,
+ const struct mg_str *strings, int num_strings);
+----
+Send multiple websocket frames.
+
+Like `mg_send_websocket_frame()`, but composes a frame from multiple buffers.
+
+==== mg_printf_websocket_frame()
+
+[source,c]
+----
+void mg_printf_websocket_frame(struct mg_connection *nc, int op_and_flags,
+ const char *fmt, ...);
+----
+Send websocket frame to the remote end.
+
+Like `mg_send_websocket_frame()`, but allows to create formatted message
+with `printf()`-like semantics.
+
+==== mg_send_http_chunk()
+
+[source,c]
+----
+void mg_send_http_chunk(struct mg_connection *nc, const char *buf, size_t len);
+----
+Send buffer `buf` of size `len` to the client using chunked HTTP encoding.
+This function first sends buffer size as hex number + newline, then
+buffer itself, then newline. For example,
+ `mg_send_http_chunk(nc, "foo", 3)` whill append `3\r\nfoo\r\n` string to
+the `nc->send_mbuf` output IO buffer.
+
+NOTE: HTTP header "Transfer-Encoding: chunked" should be sent prior to
+using this function.
+
+NOTE: do not forget to send empty chunk at the end of the response,
+to tell the client that everything was sent. Example:
+
+```
+ mg_printf_http_chunk(nc, "%s", "my response!");
+ mg_send_http_chunk(nc, "", 0); // Tell the client we're finished
+```
+
+==== mg_printf_http_chunk()
+
+[source,c]
+----
+void mg_printf_http_chunk(struct mg_connection *nc, const char *fmt, ...);
+----
+Send printf-formatted HTTP chunk.
+Functionality is similar to `mg_send_http_chunk()`.
+
+==== mg_send_response_line()
+
+[source,c]
+----
+void mg_send_response_line(struct mg_connection *c, int status_code,
+ const char *extra_headers);
+----
+Send response status line.
+If `extra_headers` is not NULL, then `extra_headers` are also sent
+after the reponse line. `extra_headers` must NOT end end with new line.
+Example:
+
+ mg_send_response_line(nc, 200, "Access-Control-Allow-Origin: *");
+
+Will result in:
+
+ HTTP/1.1 200 OK\r\n
+ Access-Control-Allow-Origin: *\r\n
+
+==== mg_send_head()
+
+[source,c]
+----
+void mg_send_head(struct mg_connection *n, int status_code,
+ int64_t content_length, const char *extra_headers);
+----
+Send response line and headers.
+This function sends response line with the `status_code`, and automatically
+sends one header: either "Content-Length", or "Transfer-Encoding".
+If `content_length` is negative, then "Transfer-Encoding: chunked" header
+is sent, otherwise, "Content-Length" header is sent.
+
+NOTE: If `Transfer-Encoding` is `chunked`, then message body must be sent
+using `mg_send_http_chunk()` or `mg_printf_http_chunk()` functions.
+Otherwise, `mg_send()` or `mg_printf()` must be used.
+Extra headers could be set through `extra_headers` - and note `extra_headers`
+must NOT be terminated by a new line.
+
+==== mg_printf_html_escape()
+
+[source,c]
+----
+void mg_printf_html_escape(struct mg_connection *nc, const char *fmt, ...);
+----
+Send printf-formatted HTTP chunk, escaping HTML tags.
+
+==== mg_parse_http()
+
+[source,c]
+----
+int mg_parse_http(const char *s, int n, struct http_message *hm, int is_req);
+----
+Parse a HTTP message.
+
+`is_req` should be set to 1 if parsing request, 0 if reply.
+
+Return number of bytes parsed. If HTTP message is
+incomplete, `0` is returned. On parse error, negative number is returned.
+
+==== mg_get_http_header()
+
+[source,c]
+----
+struct mg_str *mg_get_http_header(struct http_message *hm, const char *name);
+----
+Search and return header `name` in parsed HTTP message `hm`.
+If header is not found, NULL is returned. Example:
+
+ struct mg_str *host_hdr = mg_get_http_header(hm, "Host");
+
+==== mg_http_parse_header()
+
+[source,c]
+----
+int mg_http_parse_header(struct mg_str *hdr, const char *var_name, char *buf,
+ size_t buf_size);
+----
+Parse HTTP header `hdr`. Find variable `var_name` and store it's value
+in the buffer `buf`, `buf_size`. Return 0 if variable not found, non-zero
+otherwise.
+
+This function is supposed to parse
+cookies, authentication headers, etcetera. Example (error handling omitted):
+
+ char user[20];
+ struct mg_str *hdr = mg_get_http_header(hm, "Authorization");
+ mg_http_parse_header(hdr, "username", user, sizeof(user));
+
+Return length of the variable's value. If buffer is not large enough,
+or variable not found, 0 is returned.
+
+==== mg_parse_multipart()
+
+[source,c]
+----
+size_t mg_parse_multipart(const char *buf, size_t buf_len, char *var_name,
+ size_t var_name_len, char *file_name,
+ size_t file_name_len, const char **chunk,
+ size_t *chunk_len);
+----
+Parse buffer `buf`, `buf_len` that contains multipart form data chunks.
+Store chunk name in a `var_name`, `var_name_len` buffer.
+If a chunk is an uploaded file, then `file_name`, `file_name_len` is
+filled with an uploaded file name. `chunk`, `chunk_len`
+points to the chunk data.
+
+Return: number of bytes to skip to the next chunk, or 0 if there are
+ no more chunks.
+
+Usage example:
+
+```c
+ static void ev_handler(struct mg_connection *nc, int ev, void *ev_data) {
+ switch(ev) {
+ case MG_EV_HTTP_REQUEST: {
+ struct http_message *hm = (struct http_message *) ev_data;
+ char var_name[100], file_name[100];
+ const char *chunk;
+ size_t chunk_len, n1, n2;
+
+ n1 = n2 = 0;
+ while ((n2 = mg_parse_multipart(hm->body.p + n1,
+ hm->body.len - n1,
+ var_name, sizeof(var_name),
+ file_name, sizeof(file_name),
+ &chunk, &chunk_len)) > 0) {
+ printf("var: %s, file_name: %s, size: %d, chunk: [%.*s]\n",
+ var_name, file_name, (int) chunk_len,

+[source,c]
+----
+int mg_get_http_var(const struct mg_str *buf, const char *name, char *dst,
+ size_t dst_len);
+----
+Fetch an HTTP form variable.
+
+Fetch a variable `name` from a `buf` into a buffer specified by
+`dst`, `dst_len`. Destination is always zero-terminated. Return length
+of a fetched variable. If not found, 0 is returned. `buf` must be

+Decode URL-encoded string.
+
+Source string is specified by (`src`, `src_len`), and destination is
+(`dst`, `dst_len`). If `is_form_url_encoded` is non-zero, then
+`+` character is decoded as a blank space character. This function
+guarantees to `\0`-terminate the destination. If destination is too small,
+then source string is partially decoded and `-1` is returned. Otherwise,
+a length of decoded string is returned, not counting final `\0`.
+
+==== mg_http_create_digest_auth_header()
+
+[source,c]
+----
+int mg_http_create_digest_auth_header(char *buf, size_t buf_len,
+ const char *method, const char *uri,
+ const char *auth_domain, const char *user,
+ const char *passwd);
+----
+Create Digest authentication header for client request.
+
+==== mg_connect_http()
+
+[source,c]
+----
+struct mg_connection *mg_connect_http(struct mg_mgr *mgr,
+ mg_event_handler_t event_handler,
+ const char *url,
+ const char *extra_headers,
+ const char *post_data);
+----
+Helper function that creates outbound HTTP connection.
+
+`url` is a URL to fetch. It must be properly URL-encoded, e.g. have
+no spaces, etc. By default, `mg_connect_http()` sends Connection and
+Host headers. `extra_headers` is an extra HTTP headers to send, e.g.
+`"User-Agent: my-app\r\n"`.
+If `post_data` is NULL, then GET request is created. Otherwise, POST request
+is created with the specified POST data. Note that if the data being posted
+is a form submission, the `Content-Type` header should be set accordingly
+(see example below).
+
+Examples:
+
+```c
+ nc1 = mg_connect_http(mgr, ev_handler_1, "http://www.google.com", NULL,
+ NULL);
+ nc2 = mg_connect_http(mgr, ev_handler_1, "https://github.com", NULL, NULL);
+ nc3 = mg_connect_http(
+ mgr, ev_handler_1, "my_server:8000/form_submit/",
+ "Content-Type: application/x-www-form-urlencoded\r\n",
+ "var_1=value_1&var_2=value_2");
+```
+
+==== mg_connect_http_opt()
+
+[source,c]
+----
+struct mg_connection *mg_connect_http_opt(struct mg_mgr *mgr,
+ mg_event_handler_t ev_handler,
+ struct mg_connect_opts opts,
+ const char *url,
+ const char *extra_headers,
+ const char *post_data);
+----
+Helper function that creates outbound HTTP connection.
+
+Mostly identical to mg_connect_http, but allows to provide extra parameters
+(for example, SSL parameters
+
+==== mg_serve_http()
+
+[source,c]
+----
+void mg_serve_http(struct mg_connection *nc, struct http_message *hm,
+ struct mg_serve_http_opts opts);
+----
+Serve given HTTP request according to the `options`.
+
+Example code snippet:
+
+```c
+static void ev_handler(struct mg_connection *nc, int ev, void *ev_data) {
+ struct http_message *hm = (struct http_message *) ev_data;
+ struct mg_serve_http_opts opts = { .document_root = "/var/www" }; // C99
+
+ switch (ev) {
+ case MG_EV_HTTP_REQUEST:
+ mg_serve_http(nc, hm, opts);
+ break;
+ default:
+ break;
+ }
+}
+```
+
+==== mg_register_http_endpoint()
+
+[source,c]
+----
+void mg_register_http_endpoint(struct mg_connection *nc, const char *uri_path,
+ mg_event_handler_t handler);
+----
+Register callback for specified http endpoint
+Note: if callback is registered it is called instead of
+callback provided in mg_bind
+
+Example code snippet:
+
+```c
+static void handle_hello1(struct mg_connection *nc, int ev, void *ev_data) {
+ (void) ev; (void) ev_data;
+ mg_printf(nc, "HTTP/1.0 200 OK\r\n\r\n[I am Hello1]");
+ nc->flags |= MG_F_SEND_AND_CLOSE;
+}
+
+static void handle_hello1(struct mg_connection *nc, int ev, void *ev_data) {
+ (void) ev; (void) ev_data;
+ mg_printf(nc, "HTTP/1.0 200 OK\r\n\r\n[I am Hello2]");
+ nc->flags |= MG_F_SEND_AND_CLOSE;
+}
+
+void init() {
+ nc = mg_bind(&mgr, local_addr, cb1);
+ mg_register_http_endpoint(nc, "/hello1", handle_hello1);
+ mg_register_http_endpoint(nc, "/hello1/hello2", handle_hello2);
+}
+```
+
+==== mg_file_upload_handler()
+
+[source,c]
+----
+void mg_file_upload_handler(struct mg_connection *nc, int ev, void *ev_data,
+ mg_fu_fname_fn local_name_fn);
+----
+File upload handler.
+This handler can be used to implement file uploads with minimum code.
+This handler will process MG_EV_HTTP_PART_* events and store file data into
+a local file.
+`local_name_fn` will be invoked with whatever name was provided by the client
+and will expect the name of the local file to open. Return value of NULL will
+abort file upload (client will get a "403 Forbidden" response). If non-null,
+the returned string must be heap-allocated and will be freed by the caller.
+Exception: it is ok to return the same string verbatim.
+
+Example:
+
+```c
+struct mg_str upload_fname(struct mg_connection *nc, struct mg_str fname) {
+ // Just return the same filename. Do not actually do this except in test!
+ // fname is user-controlled and needs to be sanitized.
+ return fname;
+}
+void ev_handler(struct mg_connection *nc, int ev, void *ev_data) {
+ switch (ev) {
+ ...
+ case MG_EV_HTTP_PART_BEGIN:
+ case MG_EV_HTTP_PART_DATA:
+ case MG_EV_HTTP_PART_END:
+ mg_file_upload_handler(nc, ev, ev_data, upload_fname);
+ break;
+ }
+}
+```

+<div class="paragraph">
+<p>Mongoose is a multi-protocol networking library that implements non-blocking,
+asyncronous IO and provides event-based API. It has three basic data structures:</p>
+</div>
+<div class="ulist">
+<ul>
+<li>
+<p><a href="#_struct_mg_mgr"><code>struct mg_mgr</code></a> is an event manager
+that holds all active connections</p>
+</li>
+<li>
+<p><a href="#_struct_mg_connection"><code>struct mg_connection</code></a> describes a connection</p>
+</li>
+<li>
+<p><a href="#_struct_mbuf"><code>struct mbuf</code></a> describes data buffer
+(received or sent data)</p>
+</li>
+</ul>
+</div>
+<div class="paragraph">
+<p>Connections could be either <strong>listening</strong>, <strong>outbound</strong> or <strong>inbound</strong>.
+Outbound connections are created by <a href="#_mg_connect"><code>mg_connect()</code></a> call.
+Listening connections are created by <a href="#_mg_bind"><code>mg_bind()</code></a> call.
+Inbound connections are those accepted by a listening connection.
+Each connection is described by
+<a href="#_struct_mg_connection"><code>struct mg_connection</code></a> structure, which has
+a number of fields like socket, event handler function, send/receive buffer,
+flags, et cetera.</p>
+</div>
+<div class="paragraph">
+<p>Mongoose usage pattern is to declare and initialize event manager, create
+connections and create an event loop by calling
+<a href="#_mg_mgr_poll"><code>mg_mgr_poll()</code></a> in a loop.
+<a href="#_mg_mgr_poll"><code>mg_mgr_poll()</code></a> iterates over all sockets,
+accepts new connections, sends and receives data, closes connections,
+and calls event handler functions for the respective events.</p>
+</div>
+<div class="sect2">
+<h3 id="_memory_buffers">Memory buffers</h3>
+<div class="paragraph">
+<p>Each connection has send and receive buffer,
+<a href="#_struct_mg_connection"><code>struct mg_connection::send_mbuf</code></a>
+and
+<a href="#_struct_mg_connection"><code>struct mg_connection::recv_mbuf</code></a> respectively.
+When data arrives,
+Mongoose appends received data to the <code>recv_mbuf</code> and
+triggers <code>MG_EV_RECV</code> event. User may send data back by calling one of the
+output functions, like <a href="#_mg_send"><code>mg_send()</code></a> or
+<a href="#_mg_printf"><code>mg_printf()</code></a>. Output functions append data to the
+<code>send_mbuf</code>. When Mongoose
+successfully writes data to the socket, it discards data from
+<a href="#_struct_mg_connection"><code>mg_connection::send_mbuf</code></a> and
+sends <code>MG_EV_SEND</code> event. When connection is closed, <code>MG_EV_CLOSE</code> event is sent.</p>

+<div class="paragraph">
+<p>Each connection has an event handler function associated with it. That
+function must be implemented by user. Event handler is the key element of
+the Mongoose application, since it defines application’s behavior. This is how
+an event handler function looks like:</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre class="pygments highlight"><code data-lang="c">static void ev_handler(struct mg_connection *nc, int ev, void *ev_data) {

+<dd>
+<p>Event number, defined in <code>mongoose.h</code>. For example, when data arrives
+on inbound connection <code>ev</code> would be <code>MG_EV_RECV</code>.</p>
+</dd>
+<dt class="hdlist1">void *ev_data</dt>
+<dd>
+<p>This pointer points to the event-specific data, and it has different
+meaning for different events. For example, for <code>MG_EV_RECV</code> event,
+<code>ev_data</code> is an <code>int *</code> pointer, pointing to the number of bytes received
+from the remote peer and saved into the receive IO buffer. Exact meaning
+of <code>ev_data</code> is described for each event. Protocol-specific events usually
+have <code>ev_data</code> pointing to structures that hold protocol-specific information.</p>

+

+void mg_mqtt_broker_init(struct mg_mqtt_broker *brk, void *user_data);
+----
+Initialize a MQTT broker.
+
+==== mg_mqtt_broker()
+
+[source,c]
+----
+void mg_mqtt_broker(struct mg_connection *brk, int ev, void *data);
+----
+Process a MQTT broker message.
+
+Listening connection expects a pointer to an initialized `mg_mqtt_broker`
+structure in the `user_data` field.
+
+Basic usage:
+
+```c
+mg_mqtt_broker_init(&brk, NULL);
+
+if ((nc = mg_bind(&mgr, address, mg_mqtt_broker)) == NULL) {
+ // fail;
+}
+nc->user_data = &brk;
+```
+
+New incoming connections will receive a `mg_mqtt_session` structure
+in the connection `user_data`. The original `user_data` will be stored
+in the `user_data` field of the session structure. This allows the user
+handler to store user data before `mg_mqtt_broker` creates the session.
+
+Since only the MG_EV_ACCEPT message is processed by the listening socket,
+for most events the `user_data` will thus point to a `mg_mqtt_session`.
+
+==== mg_mqtt_next()
+
+[source,c]
+----
+struct mg_mqtt_session *mg_mqtt_next(struct mg_mqtt_broker *brk,
+ struct mg_mqtt_session *s);
+----
+Iterate over all mqtt sessions connections. Example:
+
+```c
+struct mg_mqtt_session *s;
+for (s = mg_mqtt_next(brk, NULL); s != NULL; s = mg_mqtt_next(brk, s)) {
+ // Do something
+}
+```

+Pass a message of a given length to all connections.
+
+Must be called from a thread that does NOT call `mg_mgr_poll()`.
+Note that `mg_broadcast()` is the only function
+that can be, and must be, called from a different (non-IO) thread.
+
+`func` callback function will be called by the IO thread for each

+Create a connection, associate it with the given socket and event handler,
+and add to the manager.
+
+See the `mg_add_sock_opts` structure for a description of the options.
+
+==== mg_bind()
+
+[source,c]
+----
+struct mg_connection *mg_bind(struct mg_mgr *, const char *,
+ mg_event_handler_t);
+----
+Create listening connection.
+
+See `mg_bind_opt` for full documentation.
+
+==== mg_bind_opt()
+
+[source,c]
+----
+struct mg_connection *mg_bind_opt(struct mg_mgr *mgr, const char *address,
+ mg_event_handler_t handler,
+ struct mg_bind_opts opts);
+----
+Create listening connection.
+
+`address` parameter tells which address to bind to. It's format is the same
+as for the `mg_connect()` call, where `HOST` part is optional. `address`
+can be just a port number, e.g. `:8000`. To bind to a specific interface,
+an IP address can be specified, e.g. `1.2.3.4:8000`. By default, a TCP
+connection is created. To create UDP connection, prepend `udp://` prefix,
+e.g. `udp://:8000`. To summarize, `address` paramer has following format:
+`[PROTO://][IP_ADDRESS]:PORT`, where `PROTO` could be `tcp` or `udp`.
+
+See the `mg_bind_opts` structure for a description of the optional
+parameters.
+
+Return a new listening connection, or `NULL` on error.
+NOTE: Connection remains owned by the manager, do not free().
+
+==== mg_connect()
+
+[source,c]
+----
+struct mg_connection *mg_connect(struct mg_mgr *mgr, const char *address,
+ mg_event_handler_t handler);
+----
+Connect to a remote host.
+
+See `mg_connect_opt()` for full documentation.
+
+==== mg_connect_opt()
+
+[source,c]
+----
+struct mg_connection *mg_connect_opt(struct mg_mgr *mgr, const char *address,
+ mg_event_handler_t handler,
+ struct mg_connect_opts opts);
+----
+Connect to a remote host.
+
+`address` format is `[PROTO://]HOST:PORT`. `PROTO` could be `tcp` or `udp`.
+`HOST` could be an IP address,
+IPv6 address (if Mongoose is compiled with `-DMG_ENABLE_IPV6`), or a host
+name. If `HOST` is a name, Mongoose will resolve it asynchronously. Examples
+of valid addresses: `google.com:80`, `udp://1.2.3.4:53`, `10.0.0.1:443`,
+`[::1]:80`
+
+See the `mg_connect_opts` structure for a description of the optional
+parameters.
+
+Returns a new outbound connection, or `NULL` on error.
+
+NOTE: Connection remains owned by the manager, do not free().
+
+NOTE: To enable IPv6 addresses, `-DMG_ENABLE_IPV6` should be specified
+in the compilation flags.
+
+NOTE: New connection will receive `MG_EV_CONNECT` as it's first event
+which will report connect success status.
+If asynchronous resolution fail, or `connect()` syscall fail for whatever
+reason (e.g. with `ECONNREFUSED` or `ENETUNREACH`), then `MG_EV_CONNECT`
+event report failure. Code example below:
+
+```c
+static void ev_handler(struct mg_connection *nc, int ev, void *ev_data) {
+ int connect_status;
+
+ switch (ev) {
+ case MG_EV_CONNECT:
+ connect_status = * (int *) ev_data;
+ if (connect_status == 0) {
+ // Success
+ } else {
+ // Error
+ printf("connect() error: %s\n", strerror(connect_status));
+ }
+ break;
+ ...
+ }
+}
+
+ ...
+ mg_connect(mgr, "my_site.com:80", ev_handler);
+```
+
+==== mg_set_ssl()
+
+[source,c]
+----
+const char *mg_set_ssl(struct mg_connection *nc, const char *cert,
+ const char *ca_cert);
+----
+Enable SSL for a given connection.
+`cert` is a server certificate file name for a listening connection,
+or a client certificate file name for an outgoing connection.
+Certificate files must be in PEM format. Server certificate file
+must contain a certificate, concatenated with a private key, optionally
+concatenated with parameters.
+`ca_cert` is a CA certificate, or NULL if peer verification is not
+required.
+Return: NULL on success, or error message on error.
+
+==== mg_send()
+
+[source,c]
+----
+void mg_send(struct mg_connection *, const void *buf, int len);
+----
+Send data to the connection.
+
+Note that sending functions do not actually push data to the socket.
+They just append data to the output buffer. MG_EV_SEND will be delivered when
+the data has actually been pushed out.
+
+==== mg_printf()
+
+[source,c]
+----
+int mg_printf(struct mg_connection *, const char *fmt, ...);
+----
+Send `printf`-style formatted data to the connection.
+
+See `mg_send` for more details on send semantics.
+
+==== mg_vprintf()
+
+[source,c]
+----
+int mg_vprintf(struct mg_connection *, const char *fmt, va_list ap);
+----
+Same as `mg_printf()`, but takes `va_list ap` as an argument.
+
+==== mg_socketpair()
+
+[source,c]
+----
+int mg_socketpair(sock_t[2], int sock_type);
+----
+Create a socket pair.
+`sock_type` can be either `SOCK_STREAM` or `SOCK_DGRAM`.
+Return 0 on failure, 1 on success.
+
+==== mg_check_ip_acl()
+
+[source,c]
+----
+int mg_check_ip_acl(const char *acl, uint32_t remote_ip);
+----
+Verify given IP address against the ACL.
+
+`remote_ip` - an IPv4 address to check, in host byte order
+`acl` - a comma separated list of IP subnets: `x.x.x.x/x` or `x.x.x.x`.
+Each subnet is
+prepended by either a - or a + sign. A plus sign means allow, where a
+minus sign means deny. If a subnet mask is omitted, such as `-1.2.3.4`,
+this means to deny only that single IP address.
+Subnet masks may vary from 0 to 32, inclusive. The default setting
+is to allow all accesses. On each request the full list is traversed,
+and the last match wins. Example:
+
+`-0.0.0.0/0,+192.168/16` - deny all acccesses, only allow 192.168/16 subnet
+
+To learn more about subnet masks, see the
+link:https://en.wikipedia.org/wiki/Subnetwork[Wikipedia page on Subnetwork]
+
+Return -1 if ACL is malformed, 0 if address is disallowed, 1 if allowed.
+
+==== mg_enable_multithreading()
+
+[source,c]
+----
+void mg_enable_multithreading(struct mg_connection *nc);
+----
+Enable multi-threaded handling for the given listening connection `nc`.
+For each accepted connection, Mongoose will create a separate thread
+and run event handler in that thread. Thus, if an event hanler is doing
+a blocking call or some long computation, that will not slow down
+other connections.
+
+==== mg_enable_javascript()
+
+[source,c]
+----
+enum v7_err mg_enable_javascript(struct mg_mgr *m, struct v7 *v7,
+ const char *init_js_file_name);
+----
+Enable server-side JavaScript scripting.
+Requires `-DMG_ENABLE_JAVASCRIPT` compilation flag, and V7 engine sources.
+v7 instance must not be destroyed during manager's lifetime.
+Return V7 error.
+
+==== mg_set_timer()
+
+[source,c]
+----
+double mg_set_timer(struct mg_connection *c, double timestamp);
+----
+Schedule MG_EV_TIMER event to be delivered at `timestamp` time.
+`timestamp` is a UNIX time (a number of seconds since Epoch). It is
+`double` instead of `time_t` to allow for sub-second precision.
+Return the old timer value.
+
+Example: set connect timeout to 1.5 seconds:
+
+```
+ c = mg_connect(&mgr, "cesanta.com", ev_handler);
+ mg_set_timer(c, mg_time() + 1.5);
+ ...
+
+ void ev_handler(struct mg_connection *c, int ev, void *ev_data) {
+ switch (ev) {
+ case MG_EV_CONNECT:
+ mg_set_timer(c, 0); // Clear connect timer
+ break;
+ case MG_EV_TIMER:
+ log("Connect timeout");
+ c->flags |= MG_F_CLOSE_IMMEDIATELY;
+ break;
+```
+
+==== mg_time()
+
+[source,c]
+----
+double mg_time();
+----
+A sub-second precision version of time().

+Convert connection's local or remote address into string.
+
+The `flags` parameter is a bit mask that controls the behavior,
+see `MG_SOCK_STRINGIFY_*` definitions.
+
+- MG_SOCK_STRINGIFY_IP - print IP address
+- MG_SOCK_STRINGIFY_PORT - print port number
+- MG_SOCK_STRINGIFY_REMOTE - print remote peer's IP/port, not local address
+
+If both port number and IP address are printed, they are separated by `:`.
+If compiled with `-DMG_ENABLE_IPV6`, IPv6 addresses are supported.
+
+==== mg_sock_to_str()
+
+[source,c]
+----
+void mg_sock_to_str(sock_t sock, char *buf, size_t len, int flags);
+----

+==== mg_sock_addr_to_str()
+
+[source,c]
+----
+void mg_sock_addr_to_str(const union socket_address *sa, char *buf, size_t len,
+ int flags);
+----
+Convert socket's address into string.
+
+`flags` is MG_SOCK_STRINGIFY_IP and/or MG_SOCK_STRINGIFY_PORT.
+
+==== mg_hexdump()
+
+[source,c]
+----
+int mg_hexdump(const void *buf, int len, char *dst, int dst_len);
+----

+
+Takes a memory buffer `buf` of length `len` and creates a hex dump of that
+buffer in `dst`. Generated output is a-la hexdump(1).
+Return length of generated string, excluding terminating `\0`. If returned
+length is bigger than `dst_len`, overflow bytes are discarded.
+
+==== mg_hexdump_connection()
+
+[source,c]
+----
+void mg_hexdump_connection(struct mg_connection *nc, const char *path,
+ const void *buf, int num_bytes, int ev);
+----
+Generates human-readable hexdump of the data sent or received by connection.
+`path` is a file name where hexdump should be written. `num_bytes` is
+a number of bytes sent/received. `ev` is one of the `MG_*` events sent to
+an event handler. This function is supposed to be called from the
+event handler.
+
+==== mg_avprintf()
+
+[source,c]
+----
+int mg_avprintf(char **buf, size_t size, const char *fmt, va_list ap);
+----
+Print message to buffer. If buffer is large enough to hold the message,
+return buffer. If buffer is to small, allocate large enough buffer on heap,
+and return allocated buffer.
+This is a supposed use case:
+
+ char buf[5], *p = buf;
+ p = mg_avprintf(&p, sizeof(buf), "%s", "hi there");
+ use_p_somehow(p);
+ if (p != buf) {
+ free(p);
+ }
+
+The purpose of this is to avoid malloc-ing if generated strings are small.
+
+==== mg_is_big_endian()
+
+[source,c]
+----
+int mg_is_big_endian(void);
+----
+Return true if target platform is big endian.

+
+[source,c]
+----
+const char *mg_next_comma_list_entry(const char *list, struct mg_str *val,
+ struct mg_str *eq_val);
+----
+A helper function for traversing a comma separated list of values.
+It returns a list pointer shifted to the next value, or NULL if the end
+of the list found.
+Value is stored in val vector. If value has form "x=y", then eq_val
+vector is initialized to point to the "y" part, and val vector length
+is adjusted to point only to "x".
+If list is just a comma separated list of entries, like "aa,bb,cc" then
+`eq_val` will contain zero-length string.
+
+The purpose of this function is to parse comma separated string without
+any copying/memory allocation.
+
+==== mg_match_prefix()
+
+[source,c]
+----
+int mg_match_prefix(const char *pattern, int pattern_len, const char *str);
+----
+Match 0-terminated string (mg_match_prefix) or string with given length
+mg_match_prefix_n against a glob pattern.

+
+==== mg_mk_str()
+
+[source,c]
+----
+struct mg_str mg_mk_str(const char *s);
+----
+A helper function for creating mg_str struct from plain C string.
+`NULL` is allowed and becomes `{NULL, 0}`.
+
+==== MG_MK_STR()
+
+[source,c]
