- * Name: sem_waitirq
- *
- * Description:
- *   This function is called when a signal is received by a task that is
- *   waiting on a semaphore.  According to the POSIX spec, "...the calling
- *   thread shall not return from the call to [sem_wait] until it either
- *   locks the semaphore or the call is interrupted by a signal."
- *
- * Parameters:
- *   wtcb    - A pointer to the TCB of the task that is waiting on a
- *             semphaphore, but has received a signal or timeout instead.
- *   errcode - EINTR if the semaphore wait was awakened by a signal;
- *             ETIMEDOUT if awakened by a timeout
- *
- * Return Value:
- *   None
- *
- * Assumptions:
- *
