Can we manually call the schedular to switch to another task before the given time slice happens in a task by dynamically allocating priority inside a task?Is it used anywhere?

Hi Richard, thanks for the response

What if I Increase the priority of another tasks inside one task, in that case also the scheduler will switch to another task before the given time slice, would’nt it?

If you do an action that makes another task a higher priority unblock task, then that operation will also switch to that task. Changing priority of an unblocked task will work, as will doing something that unblocks a higher priority task.
