This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.
Overview
The sched_rr_get_interval() function shall update 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 zero, the current execution time limit for the calling process shall be returned.
Return value
If successful, the sched_rr_get_interval() function shall return zero. Otherwise, it shall return a value of -1 and set errno to indicate the error.
Errors
The sched_rr_get_interval() function shall fail if:
- ESRCH
-
No process can be found corresponding to that specified by pid.
