CALLING SEQUENCE:

#include <pthread.h>

int pthread_attr_setschedpolicy(
  pthread_attr_t *attr,
  int             policy
);

STATUS CODES:

EINVAL: The attribute pointer argument is invalid.
EINVAL: The attribute set is not initialized.
ENOTSUP: The specified scheduler policy argument is invalid.

DESCRIPTION:

The pthread_attr_setschedpolicy routine is used to set the scheduler policy field in the thread attribute object attr to the value specified by policy.

Scheduling policies may be one of the following:

SCHED_DEFAULT
SCHED_FIFO
SCHED_RR
SCHED_SPORADIC
SCHED_OTHER

The precise meaning of each of these is discussed elsewhere in this manual.

As required by POSIX, RTEMS defines the feature symbol _POSIX_THREAD_PRIORITY_SCHEDULING to indicate that the family of routines to which this routine belongs is supported.
