As long as the nuttx task is created, it needs 3 handles for standard input 、output、 error(0,1,2)，So pre-reserve for the file list is a certain event and cannot be skipped, so why not make it static reservation? If that's the case, tasks using a static file list shouldn't exit, now using such a static file list for tasks that need to exit doesn't make sense. However, given the current requirement to enforce the use of such static lists, it would be best if there were options available. -- This is an automated message from the Apache Git Service.
