== NAME
nng_aio_stop - stop asynchronous I/O operation
== SYNOPSIS
[source, c]
-----------
#include <nng/nng.h>
void nng_aio_stop(nng_aio *aio);
-----------
== DESCRIPTION
The `nng_aio_stop()` function stops the asynchronous I/O operation
associated with _aio_ by aborting with `NNG_ECANCELED`, and then waits
for it to complete or to be completely aborted.
This is logically the equivalent of <<nng_aio_cancel#,nng_aio_cancel(3)>>
followed by <<nng_aio_wait#,nng_aio_wait(3)>>, except that the asynchronous
I/O handle may not be used for any further operations.
TIP: When multiple asynchronous I/O handles are in use and need to be
shut down, it is safest to stop all of them, before deallocating any of
this with <<nng_aio_free#,nng_aio_free(3)>>, particularly if the callbacks
might attempt to reschedule additional operations.
== RETURN VALUES
None.
== ERRORS
None.
