void nng_aio_stop(nng_aio *aio);nng_aio_stop(3)
NAME
nng_aio_stop - stop asynchronous I/O operation
SYNOPSIS
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
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.
