Description
OSSched() allows a task to call the scheduler. You would use this function after doing a series of “posts” where you specified OS_OPT_POST_NO_SCHED as a post option.
OSSched() can only be called by task-level code. Also, if the scheduler is locked (i.e., OSSchedLock() was previously called), then OSSched() will have no effect.
If a higher-priority task than the calling task is ready-to-run, OSSched() will context switch to that task.
