- * Name: pthread_setsetprio
- *
- * Description:
- * The pthread_setschedprio() function sets the scheduling priority for the
- * thread whose thread ID is given by 'thread' to the value given by 'prio'.
- * If the thread_setschedprio() function fails, the scheduling priority
- * of the target thread will not be changed.
- *
- * Inputs:
- * thread - the thread ID of the task to reprioritize.
- * prio - The new thread priority. The range of valid priority numbers is
- * from SCHED_PRIORITY_MIN through SCHED_PRIORITY_MAX.
- *
- * Return Value:
- * OK if successful, otherwise an error number. This function can
- * fail for the following reasons:
- *
- * EINVAL - prio is out of range.
- * ESRCH - thread ID does not correspond to any thread.
- *
- * Assumptions:
- *
