== NAME

|
nng_http_conn_write_req - write HTTP request
|
|
== SYNOPSIS
|
|
[source, c]
|
----
|
#include <nng/nng.h>
|
#include <nng/supplemental/http/http.h>
|
|
void nng_http_conn_write_req(nng_http_conn *conn, nng_http_req *req,
|
nng_aio *aio);
|
----
|
|
== DESCRIPTION
|
|
The `nng_http_conn_write_req()` function starts an asynchronous write of
|
the HTTP request _req_ to the connection _conn_.
|
The entire request is sent,
|
including headers, and if present, the request body data.
|
(The request body can be set with
|
xref:nng_http_req_set_data.3http.adoc[`nng_http_req_set_data()`] or
|
xref:nng_http_req_copy_data.3http.adoc[`nng_http_req_copy_data()`].)
|
|
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 xref:nng_aio_result.3.adoc[`nng_aio_result()`].
|
That result will either be zero or an error code.
|
|
NOTE: Consider using the
|
xref:nng_http_client_transact.3http.adoc[`nng_http_client_transact()`] or
|
xref:nng_http_conn_transact.3http.adoc[`nng_http_conn_transact()`] functions,
|
which provide a simpler interface for performing a complete HTTP client
|
transaction.
|
|
== RETURN VALUES
|
|
None.
|
|
== ERRORS
|
|
[horizontal]
|
`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.
