💅 iwpm_mapinfo_available — the Kernel API Manual page, bestie edition ✨

okay so real talk, we're in the Kernel API Manual (section 9, kernel-space girlies only 💅) and today's main character is iwpm_mapinfo_available. yes she's a function. yes she's iconic.

---

🌸 NAME 🌸

iwpm_mapinfo_available — literally just checks if any mapping info records are available in the hash table 🫶

no cap, that's the whole job. she looks, she tells you yes or no, she leaves. queen behaviour honestly 👑

---

⭐ SYNOPSIS ⭐

int iwpm_mapinfo_available (void );

one function, zero drama, int return. slay.

---

🎀 ARGUMENTS 🎀

• void — no arguments, bestie. none. she takes nothing, she needs nothing. ngl that's kind of a power move 😭

---

💖 DESCRIPTION 💖

so here's the vibe check: iwpm_mapinfo_available returns 1 if mapping information is available, otherwise it returns 0.

that's it. that's the whole function. binary queen. yes or no. 1 or 0. no in-between, no "it depends", no emotionally unavailable maybe energy 🙈

the way that she just knows whether mapping info is chilling in the hash table… obsessed 💜
