PTHREAD_ATTR_SETSCHEDPOLICY(3)                      Linux Programmer's Manual                     PTHREAD_ATTR_SETSCHEDPOLICY(3)



NAME
       pthread_attr_setschedpolicy,  pthread_attr_getschedpolicy  -  set/get  scheduling  policy  attribute in thread attributes
       object

SYNOPSIS
       #include <pthread.h>

       int pthread_attr_setschedpolicy(pthread_attr_t *attr, int policy);
       int pthread_attr_getschedpolicy(pthread_attr_t *attr, int *policy);

       Compile and link with -pthread.

DESCRIPTION
       The pthread_attr_setschedpolicy() function sets the scheduling policy attribute of the thread attributes object  referred
       to  by  attr to the value specified in policy.  This attribute determines the scheduling policy of a thread created using
       the thread attributes object attr.

       The  supported  values  for  policy  are  SCHED_FIFO,  SCHED_RR,  and  SCHED_OTHER,  with  the  semantics  described   in
       sched_setscheduler(2).

       The  pthread_attr_getschedpolicy()  returns  the  scheduling policy attribute of the thread attributes object attr in the
       buffer pointed to by policy.

RETURN VALUE
       On success, these functions return 0; on error, they return a nonzero error number.

ERRORS
       pthread_attr_setschedpolicy() can fail with the following error:

       EINVAL Invalid value in policy.

       POSIX.1-2001 also documents an optional ENOTSUP error ("attempt was made to set the attribute to an  unsupported  value")
       for pthread_attr_setschedpolicy().

CONFORMING TO
       POSIX.1-2001.

       See pthread_setschedparam(3).
