== Name

gun:await_body - Wait for the complete response body

== Description

[source,erlang]
----
await_body(ConnPid, StreamRef)
    -> await_body(ConnPid, StreamRef, 5000, MonitorRef)

await_body(ConnPid, StreamRef, MonitorRef)
    -> await_body(ConnPid, StreamRef, 5000, MonitorRef)

await_body(ConnPid, StreamRef, Timeout)
    -> await_body(ConnPid, StreamRef, Timeout, MonitorRef)

await_body(ConnPid, StreamRef, Timeout, MonitorRef)
    -> {ok, Body} | {ok, Body, Trailers} | {error, Reason}

ConnPid    :: pid()
StreamRef  :: reference()
MonitorRef :: reference()
Timeout    :: timeout()
Body       :: binary()
Trailers   :: [{binary(), binary()}]
Reason     :: timeout | any()
----

Wait for the complete response body.

== Arguments

ConnPid::

The pid of the Gun connection process.

StreamRef::

Identifier of the stream for the original request.

Timeout::

How long to wait for each message, in milliseconds.

MonitorRef::

Monitor for the Gun connection process.
+
A monitor is automatically created for the duration of this
call when one is not provided.

== Return value

The body is returned, possibly with trailers if the
request contained a `te: trailers` header. Error tuples
may also be returned when a timeout or an error occur.

== Changelog

* *1.0*: Function introduced.

== Examples

.Wait for the complete response body
[source,erlang]
----
StreamRef = gun:get(ConnPid, "/articles", [
    {<<"accept">>, <<"text/html;q=1.0, application/xml;q=0.1">>}
]).
{response, nofin, 200, _Headers} = gun:await(ConnPid, StreamRef).
{ok, _Body} = gun:await_body(ConnPid, StreamRef).
