* 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.
|
|
*
|
|
* Input Parameters:
|
|
* 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.
|
|
*
|
|
* Returned 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:
|
|
*
|
