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.
