Standard C Library Functions      pthread_attr_getschedpolicy(3C)



NAME
     pthread_attr_getschedpolicy,  pthread_attr_setschedpolicy  -
     get or set schedpolicy attribute

SYNOPSIS
     cc -mt [ flag... ] file... -lpthread [ library... ]
     #include 

     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 . When
     threads executing 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. Other-
     wise, 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.
