nng_aio_wait()
NAME
nng_aio_wait — wait for asynchronous I/O operation
SYNOPSIS
#include <nng/nng.h>
void nng_aio_wait(nng_aio *aio);
DESCRIPTION
The nng_aio_wait() function waits for an asynchronous I/O operation
to complete.
If the operation has not been started, or has already
completed, then it returns immediately.
If a callback was set with aio when it was allocated, then this function will not be called until the callback has completed.
important
This function should never be called from a function that itself
is a callback of an nng_aio, either this one or any other.
Doing so may result in a deadlock.
