d_path(9)

💖 NAME 💖

d_path — return the path of a dentry 🛣️✨

(hi bestie, this is d_path(9) from the Kernel API Manual — we're gonna get you fluent, fr fr 💅)

✨ SYNOPSIS ✨

char * d_path (const struct path *path , char *buf , int buflen );

🎀 ARGUMENTS 🎀

• path — path to report 🛣️
• buf — buffer to return value in 📥
• buflen — buffer length 📏

🦋 DESCRIPTION 🦋

okay so d_path converts a dentry into an ASCII path name ✨. if the entry has been deleted, the string " (deleted)" gets appended — and the manpage literally says note that this is ambiguous 🙈. that's not us being vague, that's the actual warning, bestie.

it returns a pointer into the buffer, or an error code if the path was too long 😭. important: callers should use the returned pointer, not the passed-in buffer, to use the name! fr fr. the implementation often starts at an offset into the buffer, and may leave 0 bytes at the start 💀.

also buflen should be positive — periodt 👑.
