sys_sched_rr_get_interval(9)

🎀 sys_sched_rr_get_interval(9) 🎀

okay bestie, this is a Kernel API Manual page for sys_sched_rr_get_interval(9) — the manual name is folded in right here, cute and accounted for. 💖

---

✨ NAME ✨

sys_sched_rr_get_interval — return the default time-slice of a process. slay, that’s the whole vibe. 💅

---

🦋 SYNOPSIS 🦋

long sys_sched_rr_get_interval (pid_t pid , struct __kernel_timespec
       __user * interval );

---

🌸 ARGUMENTS 🌸

two args, both important, no skipping:

• pid — pid of the process.
• interval — userspace pointer to the time-slice value.

---

💜 DESCRIPTION 💜

this syscall writes the default time-slice value of a given process into the user-space timespec buffer. literally that’s the move. ✨

a value of '0' means infinity. iconic little detail, do not forget it. 💫

---

🔥 RETURN 🔥

on success, 0, and the time-slice is in interval. otherwise, an error code. that’s the whole return situation, no cap. 💀
