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.
|
|
|
|
If an operation is in progress when this function is called, that operation
|
|
is canceled and the callback function is _not_ allowed to run.
|
|
|
|
If the callback function is already running when this function is called,
|
|
then it is allowed to complete before returning to the caller.
|
|
|
|
No new operations will be started on this _aio_.
|
|
|
|
NOTE: Calling this function means that the operation may be aborted without
|
|
completing its callback function.
|
|
|
|
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 xref:nng_aio_free.3.adoc[`nng_aio_free()`], particularly if the callbacks
|
|
might attempt to reschedule additional operations.
|
|
|
|
== RETURN VALUES
|
|
|
|
None.

|
