NAMESYNOPSIS
DESCRIPTION
RETURN VALUES
ERRORS
SEE ALSO
NAME
nng_aio_result - return result of asynchronous operation
SYNOPSIS
#include <nng/nng.h>
int nng_aio_result(nng_aio *aio);
DESCRIPTION
The nng_aio_result() returns the result of the operation associated with the handle aio . If the operation was successful, then 0 is returned. Otherwise a non-zero error code is returned.
Note
The return value from this function is undefined if the operation has not completed yet. Either call this from the handle’s completion callback, or after waiting for the operation to complete with nng_aio_wait().
RETURN VALUES
The result of the operation, either zero on success, or an error number on failure.
ERRORS
NNG_ETIMEDOUT
The operation timed out.
NNG_ECANCELED
The operation was canceled.
Various other return values are possible depending on the operation.
