== NAME
nng_aio_set_output - set output result
== SYNOPSIS
[source, c]
-----------
#include <nng/nng.h>
void nng_aio_set_output(nng_aio *aio, unsigned int index, void *result);
-----------
== DESCRIPTION
The `nng_aio_set_output()` function sets the output result at _index_
to _result_ for the asynchronous operation associated with _aio_.
The type and semantics of output results are determined by specific
operations; the operation must supply appropriate output results when
the operation completes successfully.
The valid values of _index_ range from zero (0) to three (3), as no operation
currently defined can return more than four results. (This limit could
increase in the future.)
NOTE: Note that attempts to set results with an _index_ greater than
three (3) will be ignored.
An output result set with this function may be retrieved later with
the <<nng_aio_get_output#,nng_aio_get_output(3)>> function.
== RETURN VALUES
None.
== ERRORS
None.
