nng_aio_wait3
Wait for asynchronous i/o operation
Usage
#include <nng/nng.h> void nng_aio_wait(nng_aio *aio);
Overview
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 aio, either this one or any other. Doing so may result in a deadlock.
Return values
None.
Errors
None.
