NAME
pthread_attr_getschedpolicy, pthread_attr_setschedpolicy - get or set schedpolicy attribute
SYNOPSIS
cc -mt [ flag... ] file... -lpthread [ library... ] #include <pthread.h> int pthread_attr_getschedpolicy(const pthread_attr_t *restrict attr, int *restrict policy); int pthread_attr_setschedpolicy(pthread_attr_t *attr, int policy);
DESCRIPTION
The functions pthread_attr_setschedpolicy() and pthread_attr_getschedpolicy(), respectively, set and get the schedpolicy attribute in the attr argument. Supported values of policy include SCHED_FIFO, SCHED_RR and SCHED_OTHER, which are defined by the header <sched.h>. When threads execut- ing with the scheduling policy SCHED_FIFO or SCHED_RR are waiting on a mutex, they acquire the mutex in priority order when the mutex is unlocked. See sched.h(3HEAD) for a description of all defined policy values. Valid policy values can also be obtained from pthread_getschedparam(3C) and sched_getscheduler(3C).
RETURN VALUES
If successful, the pthread_attr_setschedpolicy() and pthread_attr_getschedpolicy() functions return 0. Otherwise, an error number is returned to indicate the error.
ERRORS
The pthread_attr_setschedpolicy() or pthread_attr_getschedpolicy() function may fail if: EINVAL attr or policy is invalid.
USAGE
After these attributes have been set, a thread can be created with the specified attributes using pthread_create(). Using these routines does not affect the current running thread.
