Table of Contents

Name

pthread_setschedparam, pthread_getschedparam - control thread +scheduling +

parameters +

Synopsis

#include <pthread.h> +

int pthread_setschedparam(pthread_t target_thread, +int policy, const struct sched_param *param); +

int pthread_getschedparam(pthread_t target_thread, +int *policy, struct sched_param *param); +

Description

pthread_setschedparam sets the scheduling parameters for +the thread target_thread as indicated by policy and +param. policy can be either SCHED_OTHER +(regular, non-real-time scheduling), SCHED_RR (real-time, +round-robin) or SCHED_FIFO (real-time, first-in first-out). +param specifies the scheduling priority for the two real-time +policies. See sched_setpolicy(2) +for more information on scheduling policies. +

Pthreads-w32 only supports SCHED_OTHER and does not support +the real-time scheduling policies SCHED_RR and SCHED_FIFO. +

pthread_getschedparam retrieves the scheduling policy and +scheduling parameters for the thread target_thread and stores +them in the locations pointed to by policy and param, +respectively. +

Return Value

pthread_setschedparam and pthread_getschedparam +return 0 on success and a non-zero error code on error. +

Errors

On error, pthread_setschedparam returns the following error +codes: +

ENOTSUP +: + policy is not SCHED_OTHER.
+ EINVAL +: + One of the arguments is invalid, or the priority value specified by + param is not valid for the specified policy.
+ ESRCH +: + The target_thread is invalid or has already terminated +

+ +

+On error, pthread_getschedparam returns the following error +codes: +

ESRCH +: + the target_thread is invalid or has already terminated +
