🦋 tomoyo_get_absolute_path(9) 🦋

okay bestie, welcome to the Kernel API Manual — yes that's the manual name, it's giving official 💅 — and today's main character is tomoyo_get_absolute_path. she's a little function with one very specific job and honestly? she ate.

✨ NAME ✨

tomoyo_get_absolute_path — Get the path of a dentry but ignores chroot'ed root.

like, she'll give you the path, but she is literally not interested in your chroot'ed root. not her problem. not her business. 🙈

🎀 SYNOPSIS 🎀

char * tomoyo_get_absolute_path (const struct path *path , char * const buffer , const int buflen );

that's the whole vibe. three arguments, one char * coming back at you. no cap. ✨

🌸 ARGUMENTS 🌸

  • path — Pointer to "struct path". this is the dentry situation you're asking about, bestie. 🫶
  • buffer — Pointer to buffer to return value in. she's gonna write the answer in here, so pls actually give her somewhere to live.
  • buflen — Sizeof buffer. literally just how big your buffer is. she needs to know. don't lie to her. 💀

💖 DESCRIPTION 💖

Returns the buffer on success, an error code otherwise.

so like — slay, you get your buffer back and everything is iconic. but if something goes wrong? you get an error code instead. that's the vibe check and you did not pass it. 😭

If dentry is a directory, trailing / is appended.

yup, she adds the little slash at the end when it's a directory, because she's thoughtful like that. 🎀 a tiny finishing touch. the ribbon on the gift. obsessed.
