Name

+

sched_getscheduler - get scheduling policy (REALTIME) +

+

Synopsis

+

#include <sched.h> +

+

int sched_getscheduler(pid_t pid); +

+

Description

+

The sched_getscheduler function shall return the scheduling +policy of the process specified by pid. If the value of pid +is negative, the behavior of the sched_getscheduler function +is unspecified. +

+

The values that can be returned by sched_getscheduler are +defined in the <sched.h> header. +

+

Pthreads-w32 only supports the SCHED_OTHER policy, +which is the only value that can be returned. However, checks on pid +and permissions are performed first so that the other useful side +effects of this routine are retained.

+

If a process specified by pid exists, and if the calling +process has permission, the scheduling policy shall be returned for +the process whose process ID is equal to pid. +

+

If pid is zero, the scheduling policy shall be returned for +the calling process. +

+

Return Value

+

Upon successful completion, the sched_getscheduler function +shall return the scheduling policy of the specified process. If +unsuccessful, the function shall return -1 and set errno to +indicate the error. +

+

Errors

+

The sched_getscheduler function shall fail if: +

+
+
EPERM +
+ The requesting process does not have permission to determine the + scheduling policy of the specified process. +
+ ESRCH +
+ No process can be found corresponding to that specified by pid. +
