Mbufs are mutable/growing memory buffers, like C++ strings.
Mbuf can append data to the end of a buffer or insert data into arbitrary
position in the middle of a buffer. The buffer grows automatically when
needed.

---
Parses CoAP message and fills mg_coap_message and returns cm->flags.
This is a helper function.
NOTE: usually CoAP works over UDP, so lack of data means format error.
But, in theory, it is possible to use CoAP over TCP (according to RFC)
The caller has to check results and treat COAP_NOT_ENOUGH_DATA according to
underlying protocol:
- in case of UDP COAP_NOT_ENOUGH_DATA means COAP_FORMAT_ERROR,
- in case of TCP client can try to receive more data

---
Encodes and appends a DNS resource record to an IO buffer.
The record metadata is taken from the `rr` parameter, while the name and data
are taken from the parameters, encoded in the appropriate format depending on
record type and stored in the IO buffer. The encoded values might contain
offsets within the IO buffer. It's thus important that the IO buffer doesn't
get trimmed while a sequence of records are encoded while preparing a DNS
reply.
This function doesn't update the `name` and `rdata` pointers in the `rr`
struct because they might be invalidated as soon as the IO buffer grows
again.
Returns the number of bytes appended or -1 in case of error.

Uncompresses a DNS compressed name.

If the name is less than `dst_len` characters long, the remainder
of `dst` is terminated with `\0` characters. Otherwise, `dst` is not
terminated.
If `dst_len` is 0 `dst` can be NULL.

struct mg_dns_reply mg_dns_create_reply(struct mbuf *io,
struct mg_dns_message *msg);
---
Creates 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 the
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 a reply use `mg_dns_send_reply`.
It's possible to use a connection's send buffer as reply buffer,
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);

---
Sends 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 the size and flags of the message, 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.

struct mg_connection *mg_connect_ws(struct mg_mgr *mgr,
MG_CB(mg_event_handler_t event_handler,

---
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 header 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);

---
Attaches a built-in HTTP event handler to the given connection.
The 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_REPLY: The HTTP reply has arrived. The parsed HTTP reply is
passed as `struct http_message` through the handler's `void *ev_data`
pointer.
- MG_EV_HTTP_CHUNK: The HTTP chunked-encoding chunk has arrived.
The 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 that arrives, and it can
potentially 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 the WebSocket
handshake request. `ev_data` contains parsed HTTP request.
- MG_EV_WEBSOCKET_HANDSHAKE_DONE: server has completed the WebSocket
handshake. `ev_data` is a `struct http_message` containing the
client's request (server mode) or server's response (client).
In client mode handler can examine `resp_code`, which should be 101.
- MG_EV_WEBSOCKET_FRAME: new WebSocket frame has arrived. `ev_data` is
`struct websocket_message *`
When compiled with MG_ENABLE_HTTP_STREAMING_MULTIPART, Mongoose parses
multipart requests and splits them into separate events:
- MG_EV_HTTP_MULTIPART_REQUEST: Start of the request.
This event is sent before body is parsed. After this, the user
should expect a sequence of PART_BEGIN/DATA/END requests.
This is also the last time when headers and other request fields are
accessible.
- MG_EV_HTTP_PART_BEGIN: Start of a part of a multipart message.
Argument: mg_http_multipart_part with var_name and file_name set
(if present). No data is passed in this message.
- MG_EV_HTTP_PART_DATA: new portion of data from the multipart message.
Argument: mg_http_multipart_part. var_name and file_name are preserved,
data is available in mg_http_multipart_part.data.
- MG_EV_HTTP_PART_END: End of the current part. var_name, file_name are
the same, no data in the message. If status is 0, then the part is
properly terminated with a boundary, status < 0 means that connection
was terminated.
- MG_EV_HTTP_MULTIPART_REQUEST_END: End of the multipart request.
Argument: mg_http_multipart_part, var_name and file_name are NULL,
status = 0 means request was properly closed, < 0 means connection
was terminated (note: in this case both PART_END and REQUEST_END are
delivered).

guarantees to NUL-terminate the destination. If destination is too small,

`local_name_fn` will be invoked with whatever name was provided by the client

// Just return the same filename. Do not actually do this except in test!

Parses the HTTP header `hdr`. Finds variable `var_name` and stores its value

allocates a buffer of required size and writes it to `*buf`, similar to
asprintf(). The caller should always check whether the buffer was updated,
and free it if so.
This function is supposed to parse cookies, authentication headers, etc.
Example (error handling omitted):

char *user = user_buf;
struct mg_str *hdr = mg_get_http_header(hm, "Authorization");
mg_http_parse_header2(hdr, "username", &user, sizeof(user_buf));
// ... do something useful with user
if (user != user_buf) {

---
Parses the buffer `buf`, `buf_len` that contains multipart form data chunks.
Stores the 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

signature: |
void mg_send_head(struct mg_connection *n, int status_code,
int64_t content_length, const char *extra_headers);
---
Sends the response line and headers.
This function sends the 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`. Note `extra_headers`
must NOT be terminated by a new line.

symbol_kind: "func"
signature: |
void mg_send_http_chunk(struct mg_connection *nc, const char *buf, size_t len);
---
Sends buffer `buf` of size `len` to the client using chunked HTTP encoding.
This function sends the buffer size as hex number + newline first, then
the buffer itself, then the newline. For example,
`mg_send_http_chunk(nc, "foo", 3)` will append the `3\r\nfoo\r\n` string
to the `nc->send_mbuf` output IO buffer.
NOTE: The HTTP header "Transfer-Encoding: chunked" should be sent prior to
using this function.
NOTE: do not forget to send an 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
```

Sends the response status line.

after the response line. `extra_headers` must NOT end end with new line.
Example:
mg_send_response_line(nc, 200, "Access-Control-Allow-Origin: *");

* SSI files pattern. If not set, "**.shtml$|**.shtm$" is used.
*
* All files that match ssi_pattern are treated as SSI.
*
* Server Side Includes (SSI) is a simple interpreted server-side scripting
* language which is most commonly used to include the contents of a file
* into a web page. It can be useful when it is desirable to include a common
* piece of code throughout a website, for example, headers and footers.
*
* In order for a webpage to recognize an SSI-enabled HTML file, the
* filename should end with a special extension, by default the extension
* should be either .shtml or .shtm
*
* Unknown SSI directives are silently ignored by Mongoose. Currently,
* the following SSI directives are supported:
* &lt;!--#include FILE_TO_INCLUDE --&gt;
* &lt;!--#exec "COMMAND_TO_EXECUTE" --&gt;
* &lt;!--#call COMMAND --&gt;
*
* Note that &lt;!--#include ...> directive supports three path
*specifications:
*
* &lt;!--#include virtual="path" --&gt; Path is relative to web server root
* &lt;!--#include abspath="path" --&gt; Path is absolute or relative to the
* web server working dir
* &lt;!--#include file="path" --&gt;, Path is relative to current document
* &lt;!--#include "path" --&gt;
*
* The include directive may be used to include the contents of a file or
* the result of running a CGI script.
*
* The exec directive is used to execute
* a command on a server, and show command's output. Example:
*
* &lt;!--#exec "ls -l" --&gt;
*
* The call directive is a way to invoke a C handler from the HTML page.
* On each occurence of &lt;!--#call COMMAND OPTIONAL_PARAMS> directive,
* Mongoose calls a registered event handler with MG_EV_SSI_CALL event,
* and event parameter will point to the COMMAND OPTIONAL_PARAMS string.
* An event handler can output any text, for example by calling
* `mg_printf()`. This is a flexible way of generating a web page on
* server side by calling a C event handler. Example:
*
* &lt;!--#call foo --&gt; ... &lt;!--#call bar --&gt;
*
* In the event handler:
* case MG_EV_SSI_CALL: {
* const char *param = (const char *) ev_data;
* if (strcmp(param, "foo") == 0) {
* mg_printf(c, "hello from foo");
* } else if (strcmp(param, "bar") == 0) {
* mg_printf(c, "hello from bar");
* }

* When HTTP request is received, Mongoose constructs a file name from the
* requested URI by combining `document_root` and the URI. However, if the
* rewrite option is used and `uri_pattern` matches requested URI, then
* `document_root` is ignored. Instead, `url_file_or_directory_path` is used,
* which should be a full path name or a path relative to the web server's
* current working directory. It can also be an URI (http:// or https://)
* in which case mongoose will behave as a reverse proxy for that destination.
*
* Note that `uri_pattern`, as all Mongoose patterns, is a prefix pattern.
*
* If uri_pattern starts with `@` symbol, then Mongoose compares it with the
* HOST header of the request. If they are equal, Mongoose sets document root
* to `file_or_directory_path`, implementing virtual hosts support.
* Example: `@foo.com=/document/root/for/foo.com`
*
* If `uri_pattern` starts with `%` symbol, then Mongoose compares it with
* the listening port. If they match, then Mongoose issues a 301 redirect.
* For example, to redirect all HTTP requests to the
* HTTPS port, do `%80=https://my.site.com`. Note that the request URI is
