nng_aio_stop - stop asynchronous I/O operation
#include <nng/nng.h> void nng_aio_stop(nng_aio *aio);
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 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.
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 nng_aio_free(), particularly if the callbacks
might attempt to reschedule additional operations.
