== NAME
|
|
|
|
nng_aio_cancel - cancel asynchronous I/O operation
|
|
|
|
== SYNOPSIS
|
|
|
|
[source, c]
|
|
----
|
|
#include <nng/nng.h>
|
|
|
|
void nng_aio_cancel(nng_aio *aio);
|
|
----
|
|
|
|
== DESCRIPTION
|
|
|
|
The `nng_aio_cancel()` function aborts an operation previously started
|
|
with the handle _aio_.
|
|
If the operation is aborted, then the callback
|
|
for the handle will be called, and the function
|
|
xref:nng_aio_result.3.adoc[`nng_aio_result()`] will return the error `NNG_ECANCELED`.
|
|
|
|
This function does not wait for the operation to be fully aborted, but
|
|
returns immediately.
|
|
|
|
If no operation is currently in progress (either because it has already
|
|
finished, or no operation has been started yet), then this function
|
|
has no effect.
|
|
|
|
NOTE: This function is the same as calling
|
|
xref:nng_aio_abort.3.adoc[`nng_aio_abort()`] with the error `NNG_ECANCELED`.
|
|
|
|
== RETURN VALUES
|
|
|
|
None.
|
|
|
|
== ERRORS
|
|
|
|
None.
