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
           aio, either this one or any other. Doing so may result in a deadlock.

RETURN VALUES

       None.

ERRORS

       None.
