Get the execution time limit of a process
#include <sched.h>
int sched_rr_get_interval(
pid_t pid,
struct timespec * interval );
- 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.

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.
- 0
- Success.
- -1
- An error occurred (errno is set).
- ENOSYS
- The sched_rr_get_interval() function isn't currently supported.
- ESRCH
- The process pid can't be found.
