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.
