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