It should be calledonce after the AIO library has been initialized. It spawns<i>numTasks</i> system I/O tasks to be executed at <i>taskPrio</i> priority level,with a stack size of <i>taskStackSize</i>. It also starts the wait task and sets the system driver as the default driver for AIO. If <i>numTasks</i>, <i>taskPrio</i>,or <i>taskStackSize</i> is 0, a default value (<b>AIO_IO_TASKS_DFLT</b>, <b>AIO_IO_PRIO_DFLT</b>,or <b>AIO_IO_STACK_DFLT</b>, respectively) is used.<p></blockquote><h4>RETURNS</h4><blockquote><p>OK if successful, otherwise ERROR.</blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./aioSysDrv.html#top">aioSysDrv</a></b></body></html>⌨️ 快捷键说明
