C++ (Cpp) async_set_result Examples

Example #1

File: async.c Project: AmesianX/wine

/* notifies client thread of new status of its async request */
void async_terminate( struct async *async, unsigned int status )
{
    assert( status != STATUS_PENDING );

    if (async->status != STATUS_PENDING)
    {
        /* already terminated, just update status */
        async->status = status;
        return;
    }

    async->status = status;

    if (async->data.callback)
    {
        apc_call_t data;

        memset( &data, 0, sizeof(data) );
        data.type            = APC_ASYNC_IO;
        data.async_io.func   = async->data.callback;
        data.async_io.user   = async->data.arg;
        data.async_io.sb     = async->data.iosb;
        data.async_io.status = status;
        thread_queue_apc( async->thread, &async->obj, &data );
    }
    else async_set_result( &async->obj, STATUS_SUCCESS, 0, 0, 0 );

    async_reselect( async );
    release_object( async );  /* so that it gets destroyed when the async is done */
}

Example #2
