✨ iwpm_valid_pid(9) ✨

okay so bestie, welcome to the iwpm_valid_pid page from the Kernel API Manual, section 9 — yes we're in the kernel-internals part of the group chat now, and honestly? it's giving cozy little helper function energy 🎀

---

🌸 NAME 🌸

iwpm_valid_pid — the tiny vibe check that tells you whether the userspace iwarp port mapper pid is valid 💅

---

🦋 SYNOPSIS 🦋

int iwpm_valid_pid (void );

---

🍓 ARGUMENTS 🍓

• void — no arguments. that's it. nothing. nada. she takes zero parameters and she is iconic for it 🙈

---

⭐ DESCRIPTION ⭐

so here's the whole deal, no cap: this function returns true if the pid is greater than zero, and otherwise it returns false ✨

that's literally the entire personality. zero is not it, negative is not it, anything above zero? valid, slay, main character 👑
