trace_seq_path(9)

📦 version 7.3.1, in nixpkgs unstable

✨ trace_seq_path(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this page is literally all about trace_seq_path(9) and it's gonna be so good, i promise 🫶

🌸 NAME 🌸

trace_seq_path — copy a path into the sequence buffer 🎀

🦋 SYNOPSIS 🦋

int trace_seq_path (struct trace_seq *s , const struct path *path );

like, that's the whole signature, no cap ✨

💖 ARGUMENTS 💖

  • s — the trace sequence descriptor 🧚
  • path — the path you wanna write into the sequence buffer 🌸

💅 DESCRIPTION 💅

okay so basically: you write a path name into the sequence buffer. that's the vibe ✨

now for the returns, because this part is lowkey important 👑

  • Returns 1 if we successfully wrote all the contents to the buffer 🔥 slay, ate, no crumbs
  • Returns 0 if the length we need to write is bigger than the reserved buffer space 😭 in this case, nothing gets written. like, nothing at all. the buffer stays untouched, bestie 💀
real talk: that 0 return is your lil heads-up that your path didn't fit, and since nothing gets written, don't go assuming half of it made it in 🙈

🌈 SEE ALSO 🌈
