pthread_attr_getschedpolicy(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(const 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(7).
The pthread_attr_getschedpolicy() returns the scheduling policy
attribute of the thread attributes object attr in the buffer pointed to
by policy.
In order for the policy setting made by pthread_attr_setschedpolicy()
to have effect when calling pthread_create(3), the caller must use
pthread_attr_setinheritsched(3) to set the inherit-scheduler attribute
of the attributes object attr to PTHREAD_EXPLICIT_SCHED.
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 also documents an optional ENOTSUP error ("attempt was made to
set the attribute to an unsupported value") for pthread_attr_setsched‐
policy().
