pthread_getschedparam
PTHREAD_SCHEDPARAM(3) BSD Library Functions Manual PTHREAD_SCHEDPARAM(3)
NAME
pthread_setschedparam, pthread_getschedparam -- thread scheduling parameter manipulation
LIBRARY
POSIX Threads Library (libpthread, -lpthread)
SYNOPSIS
#include <pthread.h>
int
pthread_setschedparam(pthread_t thread, int policy, const struct sched_param *param);
int
pthread_getschedparam(pthread_t thread, int *policy, struct sched_param *param);
DESCRIPTION
The pthread_setschedparam() and pthread_getschedparam() functions set and get the scheduling parameters of individual threads. The schedul-
ing policy for a thread can either be SCHED_FIFO (first in, first out), SCHED_RR (round-robin), or SCHED_OTHER (timesharing). Valid thread
priorities (accessed via param->sched_priority) must be within the range returned by the sched_get_priority_min(2) and
sched_get_priority_max(2) system calls.
RETURN VALUES
If successful, these functions return 0. Otherwise, an error number is returned to indicate the error.
ERRORS
The pthread_setschedparam() function will fail if:
[EINVAL] Invalid value for policy.
[ENOTSUP] Invalid value for scheduling parameters.
[ESRCH] Non-existent thread thread.
The pthread_getschedparam() function will fail if:
[ESRCH] Non-existent thread thread.
SEE ALSO
sched_get_priority_max(2), sched_get_priority_min(2)
STANDARDS
The pthread_setschedparam() and pthread_getschedparam() functions conform to Version 2 of the Single UNIX Specification (``SUSv2'').
