PTHREAD_SCHEDPARAM(3) FreeBSD 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 * restrict policy,
struct sched_param * restrict param);
DESCRIPTION
The pthread_setschedparam() and pthread_getschedparam() functions set and
get the scheduling parameters of individual threads. The scheduling
policy for a thread can be:
SCHED_FIFO First in, first out.
SCHED_RR Round-robin.
SCHED_OTHER The system default.
The thread priority (accessed via param->sched_priority) must be at least
PTHREAD_MIN_PRIORITY and no more than PTHREAD_MAX_PRIORITY.
RETURN VALUES
If successful, these functions return 0. Otherwise, an error number is
returned to indicate the error.
ERRORS
pthread_setschedparam() may fail if:
[EINVAL] The value specified by policy is invalid.
[ENOTSUP] Invalid value for scheduling parameters.
[ESRCH] Non-existent thread thread.
pthread_getschedparam() may fail if:
[ESRCH] Non-existent thread thread.
SEE ALSO
pthread_attr_getschedparam(3), sched(3)
STANDARDS
Both functions conform to IEEE Std 1003.1-2001 ("POSIX.1").
