SYNOPSIS
#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.
Any HTTP entity/body data associated with the response is not read
automatically.
The caller should use
nng_http_conn_read_all 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().
That result will either be zero or an error code.
Consider using the
nng_http_client_transact() or
nng_http_conn_transact() functions,
which provide a simpler interface for performing a complete HTTP client
transaction.
