NAME

       nng_aio_set_input - set input parameter

SYNOPSIS

           #include <nng/nng.h>

           void nng_aio_set_input(nng_aio *aio, unsigned int index, void *param);

DESCRIPTION

       The nng_aio_set_input() function sets the input parameter at index to param for the asynchronous
       operation associated with aio.

       The type and semantics of input parameters are determined by specific operations; the caller must supply
       appropriate inputs for the operation to be performed.

       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.)

           Note

           If the index does not correspond to a defined input for the operation, then this function will have
           no effect.

           Important

           It is an error to call this function while the aio is currently in use by an active asynchronous
           operation.

       An input parameter set with this function may be retrieved later with the nng_aio_get_input() function.

RETURN VALUES

       None.

ERRORS

       None.
