sched_getparam(3C)					   Standard C Library Functions 					sched_getparam(3C)

NAME
sched_getparam - get scheduling parameters SYNOPSIS
#include <sched.h> int sched_getparam(pid_t pid, struct sched_param *param); DESCRIPTION
The sched_getparam() function returns the scheduling parameters of a process specified by pid in the sched_param structure pointed to by param. The only required member of param is sched_priority. If a process specified by pid exists and if the calling process has permission, the scheduling parameters for the process whose process ID is equal to pid will be returned. If pid is 0, the scheduling parameters for the calling process will be returned. The behavior of the sched_getparam() function is unspeci- fied if the value of pid is negative. RETURN VALUES
Upon successful completion, the sched_getparam() function returns 0. If the call to sched_getparam() is unsuccessful, the function returns -1 and sets errno to indicate the error. ERRORS
The sched_getparam() function will fail if: EPERM The requesting process does not have permission to obtain the scheduling parameters of the specified process. ESRCH No process can be found corresponding to that specified by pid. ATTRIBUTES

NAME
sched_getscheduler - get scheduling policy SYNOPSIS
#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(3C) 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: 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
