Working of Pthread Priority In Operating System: A thread ID distinctively recognizes each thread. When threads are formed, they initiate to pass parameters The returned priority value is that set by the most recent pthread_setschedparam(), pthread_setschedprio(3), or pthread_create(3) call that affected thread.Priority inversion occurs when multiple threads of various scheduling priorities all compete for a common mutex. A higher priority thread may find that a lower If you find that the current setting is “NO” then you need to rebuild EPICS base ( make clean uninstall; make ) after changing to “YES”. Since engaging the #include <pthread.h> #include <sched.h> int Note: Do not use pthread_setschedparam() to set the priority of a thread if you also use another mechanism You can set the priority attribute before creating the thread. #include <pthread.h> #include <sched.h> pthread_attr_t tattr ; pthread_t tid ; int ret The pthread_setschedprio() function shall set the scheduling priority for the thread whose thread ID is given by thread to the value given by prio.
