ptrace_event(9)

💅 ptrace_event(9) 💅

Okay so welcome to the Kernel API Manual, bestie — this is the page for ptrace_event, and it’s giving “tiny function, very specific job” energy. The NAME says it’s here to possibly stop for a ptrace event notification 👀✨

🌸 NAME 🌸

ptrace_event — possibly stop for a ptrace event notification. That’s the whole name, and honestly it ate: short, clear, no fluff 💖

✨ SYNOPSIS ✨

void ptrace_event (int event , unsigned long message );

🎀 ARGUMENTS 🎀

• event — the PTRACE_EVENT_* value to report. This is the event you’re reporting, bestie.
• message — the value for PTRACE_GETEVENTMSG to return. Yep, that exact one.

🦋 DESCRIPTION 🦋

Okay so the actual job: check whether event is enabled and, if so, report event and message to the ptrace parent. That’s it. That’s the whole slay 💅

Also, important vibe note: called without locks. No locks in the chat, bestie. The docs say it plain, so I’m saying it plain too 🫶
