nng_aio_result - return result of asynchronous operation

       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().

       NNG_ETIMEDOUT
           The operation timed out.

       NNG_ECANCELED
           The operation was canceled.

       Various other return values are possible depending on the operation.
