#include <sched.h> int sched_rr_get_interval(pid_t pid, struct timespec *interval);
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.
If successful, the sched_rr_get_interval() function returns 0. Otherwise, it returns -1 and sets errno to indicate the error.
The sched_rr_get_interval() function will fail if:
ESRCH
No process can be found corresponding to that specified by pid.
