pthread_setschedparam, pthread_getschedparam - control thread scheduling
parameters
#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);
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.
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.
pthread_setschedparam and pthread_getschedparam return 0 on success and a non-zero error code on error.
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
