SYNOPSIS
#include <nng/nng.h>
void nng_sleep_aio(nng_duration msec, nng_aio *aio);DESCRIPTION
The nng_sleep_aio() function performs an asynchronous “sleep”,
causing the callback for aio to be executed after msec milliseconds.
If the sleep finishes completely, the result will always be zero.
If a timeout is set on aio using
nng_aio_set_timeout(), and it is shorter
than msec,
then the sleep will wake up early, with a result code of NNG_ETIMEDOUT.
