cu_walk_functions_at(9)

📦 version 7.3.1, in nixpkgs unstable

💅 cu_walk_functions_at — from the Kernel API Manual (section 9)

okay so bestie, welcome to the dwarf-walking corner of the kernel, this one lives in the Kernel API Manual and it's lowkey a little tour guide for function DIEs ✨

🌸 NAME 🌸

cu_walk_functions_at — walk on function DIEs at given address 🚶‍♀️💖

✨ SYNOPSIS ✨

int cu_walk_functions_at (Dwarf_Die *cu_die , Dwarf_Addr addr , int
(*callback)(Dwarf_Die *, void *) , void *data );

🎀 ARGUMENTS 🎀

  • cu_die — a CU DIE. that's the compile-unit DIE you're strolling through, she's the main character of this whole operation 👑
  • addr — an address. the spot you're checking out 🗺️
  • callback — a callback which is called with the found DIEs. she gets handed each DIE that turns up, so be nice to her 🫶
  • data — a user data. your own little bag of stuff that rides along and gets passed through 💜

🦋 DESCRIPTION 🦋

Walk on function DIEs at given addr in cu_die. no cap, that's the whole bit: you give it a compile-unit DIE and an address, and it goes walking through the function DIEs sitting at that address.

The DIEs that get passed along should be subprogram or inlined-subroutines. like, that's the vibe check for what shows up — those are the kinds of DIEs you're going to meet on this walk 🧚‍♀️
