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.
|
Note
|
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.
|
|
Important
|
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. |
