== NAME
nng_aio_finish - finish asynchronous I/O operation
== SYNOPSIS
[source, c]
----
#include <nng/nng.h>
void nng_aio_finish(nng_aio *aio, int err);
----
== DESCRIPTION
The `nng_aio_finish()` function marks operation associated with _aio_ as
complete, with the status _err_.
This will be the result returned by
xref:nng_aio_result.3.adoc[`nng_aio_result()`].
This function causes the callback associated with the _aio_ to called.
IMPORTANT: It is mandatory that operation "`providers`" call this function
*EXACTLY ONCE* when they are finished with the operation.
After calling this function they *MUST NOT* perform any further accesses
to the _aio_.
NOTE: This function is only for I/O providers (those actually performing
the operation such as HTTP handler functions or transport providers); ordinary
users of the _aio_ should not have any need for this function.
== RETURN VALUES
None.
== ERRORS
None.
