NAME
nng_aio_get_output - return output result
SYNOPSIS
DESCRIPTION
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. |
RETURN VALUES
The indexth result of the operation, or NULL.
ERRORS
None.
