== NAME
|
|
nng_stream_listener_accept - accept incoming byte stream connection
|
|
== SYNOPSIS
|
|
[source, c]
|
----
|
#include <nng/nng.h>
|
|
void nng_stream_listener_accept(nng_stream_listener *l, nng_aio *aio);
|
----
|
|
== DESCRIPTION
|
|
The `nng_stream_listener_accept()` attempts to accept an incoming byte stream
|
connection from a remote peer, using the listener _l_.
|
The operation is completed asynchronously, using _aio_.
|
|
This operation can only be done after the listener is already
|
xref:nng_stream_listener_listen.3str.adoc[listening].
|
|
If a connection is successfully established, the _aio_ will have the
|
resulting
|
xref:nng_stream.5.adoc[`nng_stream`] object stored as its first output,
|
which can be retrieved with
|
xref:nng_aio_get_output.3.adoc[`nng_aio_get_output()`].
|
|
== RETURN VALUES
|
|
None.
|
|
== ERRORS
|
|
[horizontal]
|
`NNG_ECANCELED`:: The operation was aborted.
|
`NNG_ECLOSED`:: The listener is closed.
|
`NNG_ECONNRESET`:: The connection was reset by the peer.
|
`NNG_ENOMEM`:: Insufficient free memory exists.
|
`NNG_ESTATE`:: The listener is not not listening.
