== NAME
nng_http_conn_read_res - read HTTP response
== SYNOPSIS
[source, c]
-----------
#include <nng/nng.h>
#include <nng/supplemental/http/http.h>
void nng_http_conn_read_res(nng_http_conn *conn, nng_http_res *res,
nng_aio *aio);
-----------
== DESCRIPTION
The `nng_http_conn_read_res()` function starts an asynchronous read from the
HTTP connection _conn_, reading an HTTP response into the _res_, including all
of the related headers.
NOTE: Any HTTP entity/body data associated with the response is *not* read
automatically. The caller should use
<<nng_http_conn_read_all#,nng_http_conn_read_all(3)>> to read the entity
data, based on the details of the response itself.
This function returns immediately, with no return value. Completion of
the operation is signaled via the _aio_, and the final result may be
obtained via <<nng_aio_result#,nng_aio_result>>. That result will
either be zero or an error code.
== RETURN VALUES
None.
== ERRORS
`NNG_ECANCELED`:: The operation was canceled.
`NNG_ECLOSED`:: The connection was closed.
`NNG_ECONNRESET`:: The peer closed the connection.
`NNG_ENOMEM`:: Insufficient free memory to perform the operation.
`NNG_ENOTSUP`:: HTTP operations are not supported.
`NNG_ETIMEDOUT`:: Timeout waiting for data from the connection.
