💅 stack_trace_save_tsk — Kernel API Manual ✨

okay bestie, welcome to the manual page for stack_trace_save_tsk(9), straight out of the Kernel API Manual. it's a little function, it does one thing, and it does it iconically. let's get into it 🫶

🌸 NAME 🌸

stack_trace_save_tsk — save a task stack trace into a storage array 💾✨

like, it grabs the trace and tucks it into your array. that's the whole vibe.

🦋 SYNOPSIS 🦋

unsigned int stack_trace_save_tsk (struct task_struct *task , unsigned
long *store , unsigned int size , unsigned int skipnr );

no cap, that's the exact signature. copy it character for character or the compiler WILL come for you 😭

🎀 ARGUMENTS 🎀

  • task — the task you wanna examine 👀 like, the one whose stack trace you're snooping on (affectionately).
  • store — pointer to the storage array 📦 this is where the goods go.
  • size — size of the storage array 📏 how much room you've got to work with.
  • skipnr — number of entries to skip at the start of the stack trace 🙈 because sometimes the top of the trace is just noise and you're like "not me, not this one."

⭐ RETURN ⭐

returns the number of trace entries stored 🔥 that's it. that's the number. slay.

🧚 SEE ALSO 🧚

the friend group 💜 all of these live in the kernel file ./kernel/stacktrace.c:

and yes, some of them are listed twice — the source page said it twice so we're saying it twice. consistency is a lifestyle 💅✨

go read the source at ./kernel/stacktrace.c if you want the full lore. iykyk 🦋
