+title: Build Options
+---
+
+Mongoose source code ships in a single .c file that contains functionality
+for all supported protocols (modules). Modules can be disabled at compile
+time which reduces executable size. That can be done by setting preprocessor
+flags. Also, some preprocessor flags can be used to tune internal Mongoose
+parameters.
+
+To set a preprocessor flag during compile time, use `-D <PREPROCESSOR_FLAG>`
+compiler option. For example, to disable both MQTT and JSON-RPC,
+compile the application `my_app.c` like this (assumed UNIX system):
+
+```
+  $ cc my_app.c mongoose.c -D MG_DISABLE_MQTT -D MG_DISABLE_JSON_RPC
+```

docs/build-options/platform-spec.md

+---
+title: Platform specific
+---
+
+Mongoose tries to detect the target platform whenever possible, but in some cases you have
+to explicitly declare some peculiarities of your target, such as:
+
+- `MG_LWIP`: use LWIP networking stack
+- `MG_CC3200`: enable workarounds for the TI CC3200 target.
+- `MG_ESP8266`: enable workarounds for the ESP8266 target, add `RTOS_SDK` to specify the RTOS SDK flavour.

docs/build-options/tunables.md

+---
+title: Tunables
+---
+
+- `MG_MALLOC`, `MG_CALLOC`, `MG_REALLOC`, `MG_FREE` allow to use custom
+  memory allocator, e.g. `-DMG_MALLOC=my_malloc`
+- `MG_USE_READ_WRITE` when set replaces calls to `recv` with `read` and `send` with `write`,
+  thus enabling to add any kind of file descriptor (files, serial devices) to an event manager.
+- `MG_SSL_CRYPTO_MODERN`, `MG_SSL_CRYPTO_OLD` - choose either "Modern" or "Old" ciphers
+  instead of the default "Intermediate" setting.

+---
+
+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);

+---
+
+Append a DNS reply record to the IO buffer and to the DNS message.

+to ensure num_answers is propertly initialized.
+
+Returns -1 on error.

+---
+
+Send a DNS reply through a connection.
+
+The DNS data is stored in an IO buffer pointed by reply structure in `r`.
+This function mutates the content of that buffer in order to ensure that
+the DNS header reflects size and flags of the mssage, that might have been
+updated either with `mg_dns_reply_record` or by direct manipulation of
+`r->message`.
+
+Once sent, the IO buffer will be trimmed unless the reply IO buffer
+is the connection's send buffer and the connection is not in UDP mode.

+---
+
+Send response line and headers.

+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.

+  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

+---
+
+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_EV_HTTP_PART_END constants

+Decode URL-encoded string.
+
+Source string is specified by (`src`, `src_len`), and destination is

+guarantees to `\0`-terminate the destination. If destination is too small,
+then source string is partially decoded and `-1` is returned. Otherwise,

+symbol_kind: "func"
+signature: |
+  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`.

+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.

+  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.

+---
+
+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

+title: 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

docs/design-concept/event-handler.md

+---
+title: 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:
+
+```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: `struct mg_connection` has `void *user_data` which is a placeholder for
+an application-specific data. Mongoose does not use that pointer. Event handler
+can store any kind of information there.

 title: 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 `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 `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
+  `mbuf_remove()`, set connection flags `nc->flags` if necessary (see `struct
+  mg_connection`), and write data the remote peer by output functions like
+  `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 `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 `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 `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 `mg_set_timer()` was called.
