- * Name: task_delete
- *
- * Description:
- *   This function causes a specified task to cease to exist. Its  stack and
- *   TCB will be deallocated.  This function is the companion to task_create().
- *
- *   The logic in this function only deletes non-running tasks.  If the 'pid'
- *   parameter refers to to the currently runing task, then processing is
- *   redirected to exit().
- *
- *   Control will still be returned to task_delete() after the exit() logic
- *   finishes.  In fact, this function is the final function called all task
- *   termination sequences.  Here are all possible exit scenarios:
- *
- *   - pthread_exit().  Calls exit()
- *   - exit(). Calls _exit()
- *   - _exit().  Calls task_deletecurrent() making the currently running task
- *     non-running then calls task_delete() to terminate the non-running
- *     task.
- *   - task_delete()
- *
- * Inputs:
- *   pid - The task ID of the task to delete.  A pid of zero
- *         signifies the calling task.
- *
- * Return Value:
- *   OK on success; or ERROR on failure
- *
- *   This function can fail if the provided pid does not correspond to a
- *   task (errno is not set)
- *
