== NAME
|
|
|
|
nng_aio_free - free asynchronous I/O handle
|
|
|
|
== SYNOPSIS
|
|
|
|
[source, c]
|
|
----
|
|
#include <nng/nng.h>
|
|
|
|
void nng_aio_free(nng_aio *aio);
|
|
void nng_aio_reap(nng_aio *aio);
|
|
----
|
|
|
|
== DESCRIPTION
|
|
|
|
The `nng_aio_free()` function frees an allocated asynchronous I/O handle.
|
|
If any operation is in progress, the operation is canceled, and the
|
|
caller is blocked until the operation is completely canceled, to ensure
|
|
that it is safe to deallocate the handle and any associated resources.
|
|
(This is done by implicitly calling xref:nng_aio_stop.3.adoc[`nng_aio_stop()`].)
|
|
|
|
The `nng_aio_reap()` function is the same as `nng_aio_free()`, but does
|
|
it's work in a background thread.
|
|
This can be useful to discard the _aio_ object from within the callback for the _aio_.
|
|
|
|
IMPORTANT: Once either of these functions are called, the _aio_ object is invalid and must not be used again.
|
|
|
|
== RETURN VALUES
