NAME
nng_aio_get_input - return input parameter
SYNOPSIS
DESCRIPTION
The nng_aio_get_input() function returns the value of the input parameter
previously set at index on aio with the
nng_aio_set_input() function.
The valid values of index range from zero (0) to three (3), as no operation
currently defined can accept more than four parameters.
(This limit could increase in the future.)
If the index supplied is outside of this range,
or of the input parameter was not previously set, then NULL is returned.
RETURN VALUES
Value previously set, or NULL.
ERRORS
None.
