nng_aio_get_input(3)

NAME

nng_aio_get_input — return input parameter

SYNOPSIS

#include <nng/nng.h>

void *nng_aio_get_input(nng_aio *aio, unsigned int index);

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. If the index supplied is outside of this range, or if the input parameter was not previously set, then NULL is returned.

RETURN VALUES

Value previously set, or NULL.
