????????????? *??????????????????????????? semaphore.
????????????? *
????????????? *????????????? opt?????????? determines delete options as follows:
????????????? *??????????????????????????? opt == OS_DEL_NO_PEND?? Delete semaphore ONLY if no task pending
????????????? *??????????????????????????? opt == OS_DEL_ALWAYS??? Deletes the semaphore even if tasks are waiting.
????????????? *??????????????????????????????????????????????????? In this case, all the tasks pending will be readied.
????????????? *
????????????? *????????????? err?????????? is a pointer to an error code that can contain one of the following values:
????????????? *??????????????????????????? OS_NO_ERR?????????????? The call was successful and the semaphore was deleted
????????????? *??????????????????????????? OS_ERR_DEL_ISR????????? If you attempted to delete the semaphore from an ISR
????????????? *??????????????????????????? OS_ERR_INVALID_OPT????? An invalid option was specified
????????????? *??????????????????????????? OS_ERR_TASK_WAITING???? One or more tasks were waiting on the semaphore
????????????? *??????????????????????????? OS_ERR_EVENT_TYPE?????? If you didn't pass a pointer to a semaphore
????????????? *??????????????????????????? OS_ERR_PEVENT_NULL????? If 'pevent' is a NULL pointer.
????????????? *
????????????? * Returns??? : pevent??????? upon error
????????????? *????????????? (OS_EVENT *)0 if the semaphore was successfully deleted.
????????????? *
????????????? * Note(s)??? : 1) This function must be used with care.? Tasks that would normally expect the presence of
????????????? *???????????????? the semaphore MUST check the return code of OSSemPend().
????????????? *????????????? 2) OSSemAccept() callers will not know that the intended semaphore has been deleted unless
????????????? *???????????????? they check 'pevent' to see that it's a NULL pointer.
????????????? *????????????? 3) This call can potentially disable interrupts for a long time.? The interrupt disable
????????????? *???????????????? time is directly proportional to the number of tasks waiting on the semaphore.
????????????? *????????????? 4) Because ALL tasks pending on the semaphore will be readied, you MUST be careful in
????????????? *???????????????? applications where the semaphore is used for mutual exclusion because the resource(s)
????????????? *???????????????? will no longer be guarded by the semaphore.
