nng_aio_wait(3)

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.

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.
