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.
