nng_aio_get_output - return output result
#include <nng/nng.h> void *nng_aio_get_output(nng_aio *aio, unsigned int index);
The nng_aio_get_output() function returns the output result at index resulting from the asynchronous operation associated with aio.
The type and semantics of output parameters are determined by specific operations.
If the index does not correspond to a defined output for
the operation,
or the operation did not succeed, then the return value will be
NULL.
It is an error to call this function while the aio is
currently
in use by an active asynchronous operation, or if no operation has been
performed using the aio yet.
The indexth result of the operation, or NULL.
None.
