(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. + +== SEE ALSO + +<<nng_aio_alloc#,nng_aio_alloc(3)>>, +<<nng_aio_get_output#,nng_aio_get_output(3)>>, +<<nng_aio_set_input#,nng_aio_set_input(3)>>, +<<nng_aio_result#,nng_aio_result(3)>>, +<<nng#,nng(7)>> |
