💅 name_is_dot_dotdot(9) — Kernel API Manual ✨

okay so bestie, welcome to the name_is_dot_dotdot(9) page 🫶 this is from the Kernel API Manual and it's honestly a tiny little icon, no cap.

🌸 NAME 🌸

name_is_dot_dotdot — returns true only if @name is "." or ".." 💖

like… that's it. that's the whole vibe check. it looks at a name and goes "is this the current directory or the parent directory, yes or no" and nothing else. periodt.

---

✨ SYNOPSIS ✨

bool name_is_dot_dotdot (const char *name , size_t len );

it gives you back a bool, takes a const char * and a size_t, and it's literally not that deep 💫

---

🎀 ARGUMENTS 🎀

• name — the file name you want to check 👀 that's the thing getting the vibe check
• len — length of the file name, in bytes 📏 (bytes, bestie, not vibes)
