== 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, and for the
|
|
callback associated with the _aio_ to have completed executing.
|
|
|
|
Further calls to
|
|
xref:nng_aio_begin.3.adoc[`nng_aio_begin()`] using this _aio_ will return false.
|
|
|
|
It is safe to call this for an _aio_, even when no operation is currently
|
|
pending for it.
|
|
|
|
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
|
|
them with xref:nng_aio_free.3.adoc[`nng_aio_free()`], particularly if the callbacks
|
|
might attempt to reschedule additional operations.
|
|
|
|
== RETURN VALUES
|
|
|
|
None.
|
|
|
|
== ERRORS
|
|
|
|
None.
