name_contains_dotdot(9)

💅 NAME 💅

Hey bestie 🫶, this is name_contains_dotdot(9) from the Kernel API Manual, and it is here to check if a file name contains .. path components. That's the whole assignment — it's giving path-component detective energy, no cap. 💖✨

✨ SYNOPSIS ✨

bool name_contains_dotdot (const char *name );

Okay so it takes a const char *name and hands you back a bool, periodt. 💅

🎀 ARGUMENTS 🎀

• name — the file path string to check. It searches for .. surrounded by either '/' or the start/end of the string. So yes bestie, that exact surrounded-by-slashes-or-boundaries situation is the moment. 🔍💖
