pthread_attr_getschedpolicy

       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.
