NAME
sched_getscheduler - get scheduling policy SYNOPSIS
cc [ flag... ] file... -lrt [ library... ] #include <sched.h> int sched_getscheduler(pid_t pid); DESCRIPTION
The sched_getscheduler() function returns 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 header <sched.h> and described on the sched_setscheduler(3RT) manual page. If a process specified by pid exists and if the calling process has permission, the scheduling policy will be returned for the process whose process ID is equal to pid. If pid is 0, the scheduling policy will be returned for the calling process. RETURN VALUES
Upon successful completion, the sched_getscheduler() function returns the scheduling policy of the specified process. If unsuccessful, the function returns -1 and sets errno to indicate the error. ERRORS
The sched_getscheduler() function will fail if: ENOSYS The sched_getscheduler() function is not supported by the system. 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. ATTRIBUTES

sched_get_priority_max(3RT)				    Realtime Library Functions				       sched_get_priority_max(3RT)

NAME
sched_get_priority_max, sched_get_priority_min - get scheduling parameter limits SYNOPSIS
cc [ flag... ] file... -lrt [ library... ] #include <sched.h> int sched_get_priority_max(int policy); int sched_get_priority_min(int policy); DESCRIPTION
The sched_get_priority_max() and sched_get_priority_min() functions return the appropriate maximum or minimum, respectfully, for the sched- uling policy specified by policy. The value of policy is one of the scheduling policy values defined in <sched.h>. RETURN VALUES
If successful, the sched_get_priority_max() and sched_get_priority_min() functions return the appropriate maximum or minimum values, respectively. If unsuccessful, they return -1 and set errno to indicate the error. ERRORS
The sched_get_priority_max() and sched_get_priority_min() functions will fail if: EINVAL The value of the policy parameter does not represent a defined scheduling policy. ENOSYS The sched_get_priority_max(), sched_get_priority_min() and sched_rr_get_interval(3RT) functions are not supported by the system. ATTRIBUTES
