Realtime Library Functionssched_rr_get_interval(3RT)


NAME

 sched_rr_get_interval - get execution time limits

SYNOPSIS

 
cc [ flag... ] file... -lrt [ library... ]
#include <sched.h> 
int sched_rr_get_interval(pid_t pid, struct timespec *interval);

DESCRIPTION

 

The sched_rr_get_interval() function updates the timespec structure referenced by the interval argument to contain the current execution time limit (that is, time quantum) for the process specified by pid. If pid is 0, the current execution time limit for the calling process will be returned.

RETURN VALUES

 

If successful, the sched_rr_get_interval() function returns 0. Otherwise, it returns -1 and sets errno to indicate the error.

ERRORS

 

The sched_rr_get_interval() function will fail if:

ENOSYS
The sched_get_priority_max(3RT), sched_get_priority_min(3RT), and sched_rr_get_interval() functions are not supported by the system.
ESRCH
No process can be found corresponding to that specified by pid.

NOTES

 

Solaris 2.6 was the first release to support libposix4/librt. Prior to this release, this function always returned -1 and set errno to ENOSYS.
