== NAME
|
|
|
|
nng_aio_wait - wait for asynchronous I/O operation
|
|
|
|
== SYNOPSIS
|
|
|
|
[source, c]
|
|
----
|
|
#include <nng/nng.h>
|
|
|
|
void nng_aio_wait(nng_aio *aio);
|
|
----
|
|
|
|
== DESCRIPTION
|
|
|
|
The `nng_aio_wait()` function waits for an asynchronous I/O operation
|
|
to complete.
|
|
If the operation has not been started, or has already
|
|
completed, then it returns immediately.
|
|
|
|
If a callback was set with _aio_ when it was allocated, then this
|
|
function will not be called until the callback has completed.
|
|
|
|
IMPORTANT: This function should never be called from a function that itself
|
|
is a callback of an xref:nng_aio.5.adoc[`aio`], either this one or any other.
|
|
Doing so may result in a deadlock.
|
|
|
|
== RETURN VALUES
|
|
|
|
None.
|
|
|
|
== ERRORS
|
|
|
|
None.
