PTHREAD_ATTR_SETSCHEDPOLICY(3)Linux Programmer's ManualPTHREAD_ATTR_SETSCHEDPOLICY(3)
pthread_attr_setschedpolicy, pthread_attr_getschedpolicy - set/get scheduling
policy attribute in thread attributes object
#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.
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.
On success, these functions return 0; on error, they return a nonzero error
number.
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().
POSIX.1-2001.
