 322:os/source/os_task.c **** *
 323:os/source/os_task.c **** * Description: This function allows you to delete a task.  The calling task can delete itself by
 324:os/source/os_task.c **** *              its own priority number.  The deleted task is returned to the dormant state and can 
 325:os/source/os_task.c **** *              re-activated by creating the deleted task again.
 326:os/source/os_task.c **** *
 327:os/source/os_task.c **** * Arguments  : prio    is the priority of the task to delete.  Note that you can explicitely delete
 328:os/source/os_task.c **** *                      the current task without knowing its priority level by setting 'prio' to
 329:os/source/os_task.c **** *                      OS_PRIO_SELF.
 330:os/source/os_task.c **** *
 331:os/source/os_task.c **** * Returns    : OS_NO_ERR           if the call is successful
 332:os/source/os_task.c **** *              OS_TASK_DEL_IDLE    if you attempted to delete uC/OS-II's idle task
 333:os/source/os_task.c **** *              OS_PRIO_INVALID     if the priority you specify is higher that the maximum allowed
 334:os/source/os_task.c **** *                                  (i.e. >= OS_LOWEST_PRIO) or, you have not specified OS_PRIO_SELF
 335:os/source/os_task.c **** *              OS_TASK_DEL_ERR     if the task you want to delete does not exist
 336:os/source/os_task.c **** *              OS_TASK_DEL_ISR     if you tried to delete a task from an ISR
 337:os/source/os_task.c **** *
 338:os/source/os_task.c **** * Notes      : 1) To reduce interrupt latency, OSTaskDel() 'disables' the task:
 339:os/source/os_task.c **** *                    a) by making it not ready
 340:os/source/os_task.c **** *                    b) by removing it from any wait lists
 341:os/source/os_task.c **** *                    c) by preventing OSTimeTick() from making the task ready to run.
 342:os/source/os_task.c **** *                 The task can then be 'unlinked' from the miscellaneous structures in uC/OS-II.
 343:os/source/os_task.c **** *              2) The function OS_Dummy() is called after OS_EXIT_CRITICAL() because, on most proce
 344:os/source/os_task.c **** *                 the next instruction following the enable interrupt instruction is ignored.  
 345:os/source/os_task.c **** *              3) An ISR cannot delete a task.
 346:os/source/os_task.c **** *              4) The lock nesting counter is incremented because, for a brief instant, if the curr
 347:os/source/os_task.c **** *                 task is being deleted, the current task would not be able to be rescheduled becau
 348:os/source/os_task.c **** *                 is removed from the ready list.  Incrementing the nesting counter prevents anothe
 349:os/source/os_task.c **** *                 from being schedule.  This means that an ISR would return to the current task whi
 350:os/source/os_task.c **** *                 being deleted.  The rest of the deletion would thus be able to be completed.
