SCHED_GET_PRIORITY_MAX(3P)

💖 sched_get_priority_max(3P) — POSIX Programmer's Manual 💖

okay bestie, welcome to the POSIX Programmer's Manual, page SCHED_GET_PRIORITY_MAX(3P). before we even start, real talk:

PROLOG heads-up: this manual page is part of the POSIX Programmer's Manual. the Linux implementation of this interface may differ (so go consult the corresponding Linux manual page for the deets on Linux behavior), or honestly the interface may not be implemented on Linux at all. no cap. 🫶

✨ NAME ✨

sched_get_priority_max, sched_get_priority_min — get priority limits (REALTIME) 🔥

---

🎀 SYNOPSIS 🎀

#include <sched.h>

int sched_get_priority_max(int policy);
int sched_get_priority_min(int policy);

---

💅 DESCRIPTION 💅

so like, sched_get_priority_max() and sched_get_priority_min() shall return the appropriate maximum or minimum, respectively, for the scheduling policy specified by policy. that's it, that's the whole vibe. 🌈

and the value of policy shall be one of the scheduling policy values defined in <sched.h>. periodt. 📌

---

🦋 RETURN VALUE 🦋

if it's successful, sched_get_priority_max() and sched_get_priority_min() shall return the appropriate maximum or minimum values, respectively. slay. ✨

if it's unsuccessful?? they shall return a value of -1 and set errno to indicate the error. not the moment bestie 😭

---

🍓 ERRORS 🍓

the sched_get_priority_max() and sched_get_priority_min() functions shall fail if:

• EINVAL — the value of the policy parameter does not represent a defined scheduling policy. like, that policy is not invited to the function 💀

heads up: the following sections are informative. (so, vibe only, no rules here 💜)
