p9_parse_header(9)

📦 version 7.3.1, in nixpkgs unstable

💖 p9_parse_header(9) 💖

okay so bestie, welcome to the Kernel API Manual page for p9_parse_header — that's the function name AND the whole vibe, and yes it lives in section 9 (kernel girlies only 💅).

✨ NAME ✨

p9_parse_header — literally parses header arguments out of a packet. that's it. that's the whole job. 🎀

🦋 SYNOPSIS 🦋

int p9_parse_header (struct p9_fcall *pdu , int32_t *size , int8_t *type
, int16_t *tag , int rewind );

it's giving "five whole arguments, keep up." int goes in, magic happens, int probably comes back out. slay. 🌸

🌈 ARGUMENTS 🌈

  • pdu — the packet we're parsing, bestie. the main character of this whole operation. 👑
  • size — the size of the packet, int32_t and pointer flavored so the number can come back out to you. 📏
  • type — the type of request (int8_t, also a pointer, because we're handing you info, not gatekeeping). 🧚
  • tag — the tag of the packet, int16_t pointer, cute little 16-bitter. 🏷️
  • rewind — set this if we need to rewind the offset afterwards. yes that's the whole condition. no cap. ⏪
ok and a gentle reminder: size, type and tag are int32_t *, int8_t * and int16_t * respectively — the exact types are RIGHT THERE in the synopsis, do not come for me. 🙈

like. that's the whole 9p squad and they all ate. 🫶💯

anyway that's the page!! sourced straight from ./net/9p, dated October 2026, and the version is whatever the Kernel API Manual says it is — so like, cite it, don't fight it. mwah, bye bestie 💜💅⭐
