d_namespace_path(9)

💖 NAME 💖

okay so bestie, welcome to the d_namespace_path(9) page in the Kernel API Manual. this function is literally here to lookup a name associated with a given path. that's the whole assignment. no cap. 💅

---

✨ SYNOPSIS ✨

the whole vibe, verbatim:

int d_namespace_path (const struct path *path , char *buf , char **name
       , int flags , const char *disconnected );

---

🎀 ARGUMENTS 🎀

• path — the path to look up. it's NOT NULL, so do not come in here with a null path, bestie. 🙈
• buf — the buffer where the path gets stored. also NOT NULL. respect the buffer. 🫶
• name — returns a pointer for the start of the path name within buf. yep, NOT NULL again. 💖
• flags — flags that control the path lookup. that's the whole description she gave us, and honestly? iconic brevity. ✨
• disconnected — a string to prefix onto disconnected paths. cute little prefix era. 🎀

---

💅 DESCRIPTION 💅

this one handles path name lookup. that's it, that's the description. it's giving "I do exactly what my name says" energy, and we love that for her. no extra lore in the original, so I'm not inventing any. periodt. 🔥

---

🫶 RETURN 🫶

returns 0, else an error code if the path lookup fails. when there's no error, the path name is returned in name, and that name points to a position in buf. slay. 👑
