pthread_getschedparam

pthread_getschedparam(3C)												 pthread_getschedparam(3C)

NAME

       pthread_getschedparam, pthread_setschedparam - access dynamic thread scheduling parameters

SYNOPSIS

       cc -mt [ flag... ] file... -lpthread [ library... ]
       #include <pthread.h>

       int pthread_getschedparam(pthread_t thread, int *restrict policy, struct sched_param *restrict param);

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

       The  pthread_getschedparam()  and  pthread_setschedparam()  functions  allow  the scheduling policy and scheduling parameters of individual
       threads within a multithreaded process to be retrieved and  set.  Supported  policies  are   SCHED_FIFO,  SCHED_RR,  and  SCHED_OTHER.  See
       pthreads(5).  For SCHED_FIFO, SCHED_RR, and SCHED_OTHER, the affected scheduling parameter is the sched_priority member of the  sched_param
       structure.

       The pthread_getschedparam() function retrieves the scheduling policy and scheduling parameters for the thread whose thread  ID is given	by
       thread  and  stores  those  values in policy and param, respectively. The priority value returned from pthread_getschedparam() is the value
       specified by the most recent pthread_setschedparam() or pthread_create() call affecting the  target  thread,  and  reflects  any  temporary
       adjustments  to	its  priority  as a result of any priority inheritance or ceiling functions. The pthread_setschedparam() function sets the
       scheduling policy and associated scheduling parameters for the thread whose thread  ID is given by thread  to  the  policy  and	associated
       parameters provided in policy and param, respectively.

       If the pthread_setschedparam() function fails, no scheduling parameters will be changed	for the target thread.

       If successful, the pthread_getschedparam() and pthread_setschedparam() functions return	0. Otherwise, an error number is returned to indi-
       cate the error.

       The pthread_getschedparam() function may fail if:

       ESRCH	       The value specified by thread does not refer to a existing thread.

       The pthread_setschedparam() function may fail if:

       EINVAL	       The value specified by policy or one of the scheduling parameters associated with the scheduling policy policy is invalid.

       EPERM	       The caller does not have the appropriate permission to set either the scheduling parameters or the scheduling policy of the
		       specified thread.

       ESRCH	       The value specified by thread does not refer to a existing thread.
