tomoyo_sys_getppid(9)

💅 tomoyo_sys_getppid(9) — from the Kernel API Manual, bestie ✨

okay so picture this: it's a whole man page about one (1) tiny function, and honestly? it's iconic. this is tomoyo_sys_getppid, living its best life in the Kernel API Manual. let's get into it 🎀

---

🌸 NAME 🌸

tomoyo_sys_getppid — literally just a copy of getppid(). that's it. that's the whole vibe. no cap 💖

---

✨ SYNOPSIS ✨

pid_t tomoyo_sys_getppid (void );

she takes nothing, she returns a pid_t. lowkey perfect 🫶

---

🎀 ARGUMENTS 🎀

• void — no arguments. zero. none. she doesn't need them, she's booked and busy 💅

---

🦋 DESCRIPTION 🦋

Returns the parent process's PID. simple, clean, does exactly what it says on the tin ⭐

ok so here's the lore, and it's giving "I did it for the build" 😭 — Alpha does not have getppid defined. and because of that, to be able to build this module on Alpha, the author had to copy getppid from kernel/timer.c. yes, literally copy it. we respect the hustle 🙈
