SYNOPSIS
#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.
| Calling this function means that the operation may be aborted without completing its callback function. |
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(), particularly if the callbacks
might attempt to reschedule additional operations.
