📦 version 7.3.1, in nixpkgs unstable

💅 no_more_nodes(9)

okay so real talk bestie, this one lives in the Kernel API Manual and it's called no_more_nodes — yes the "(9)" is part of the whole name, that's just how the kernel section do 🎀

✨ NAME ✨

no_more_nodes — literally just here to tell you if there are no more nodes in a buffer. that's the whole gig, no cap 💖

🌸 SYNOPSIS 🌸

int no_more_nodes (const struct ubifs_info *c , void *buf , int len ,
int lnum , int offs );

🦋 ARGUMENTS 🦋

  • c — the UBIFS file-system description object, aka the main character of this whole situation 👑
  • buf — the buffer we're checking. yes. that one. 👀
  • len — how long that buffer is, in case you were wondering 💅
  • lnum — the LEB number of the LEB that buf was read from 🎀
  • offs — the offset that buf was read from, so you know exactly where we're at ✨

💜 DESCRIPTION 💜

so the vibe here is: this function makes sure that the corrupted node sitting at offs is legit the last thing written to a LEB. like, nothing after it, that's the end, periodt 💀

and it reports back like this:

  • returns 1 if more data is not found (slay, we're done here) 🎉
  • returns 0 if more data is found (ok so there's more, keep going bestie) 😭

that's it. that's the function. lowkey iconic for how straightforward it is ngl 🫶
