Manual Section... (3) - page: pthread_setschedprio
NAMEpthread_setschedprio - set scheduling priority of a thread
#include <pthread.h> pthread_setschedprio(pthread_t thread, int prio); Compile and link with -pthread.
DESCRIPTIONThe pthread_setschedprio() function sets the scheduling priority of the thread thread to the value specified in prio. (By contrast pthread_setschedparam(3) changes both the scheduling policy and priority of a thread.)
RETURN VALUEOn success, this function returns 0; on error, it returns a nonzero error number. If pthread_setschedprio() fails, the scheduling priority of thread is not changed.
- prio is not valid for the scheduling policy of the specified thread.
- The caller does not have appropriate privileges to set the specified priority.
- No thread with the ID thread could be found.
VERSIONSThis function is available in glibc since version 2.3.4.
NOTESFor a description of the permissions required to, and the effect of, changing a thread's scheduling priority, and details of the permitted ranges for priorities in each scheduling policy, see sched_setscheduler(2).
