sched_rr_get_interval()

Get the execution time limit of a process

Synopsis:

#include <sched.h>

int sched_rr_get_interval( 
                 pid_t pid,
                 struct timespec * interval );

Arguments:

pid: The process ID whose execution time limit you want to get.
interval: A pointer to a timespec structure that the function updates with the process's current execution time limit.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

The sched_rr_get_interval() function updates interval with the current execution time limit for the process, pid. If pid is 0, the current execution time limit for the calling process is returned.

Returns:

0: Success.
-1: An error occurred (errno is set).

Errors:

ENOSYS: The sched_rr_get_interval() function isn't currently supported.
ESRCH: The process pid can't be found.
