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.
