read_rindex_entry(9)

✨ NAME ✨

Okay so read_rindex_entry(9) — yes bestie, that's the page title, and it's from the Kernel API Manual — is literally the function that pulls in a new resource index entry from the disk. That's the vibe: new rindex entry, pulled in from disk, slay.

🌸 SYNOPSIS 🌸

int read_rindex_entry (struct gfs2_inode *ip );

🎀 ARGUMENTS 🎀

• ip — pointer to the rindex inode. That's the whole argument, bestie. Hand over the pointer and let the function do its thing.

💅 RETURN 💅

The return situation is: 0 on success, > 0 on EOF, error code otherwise. So yes, success is 0, EOF is > 0, and anything else is an error code. Noted, periodt.
