THREAD_EXIT(9)

🦋 thread_exit(9) — abandon current thread context 🦋

okay so this page is from the Kernel Developer's Manual, and the vibe is: a thread is clocking out for good 💅✨

🌸 NAME 🌸

thread_exit — abandon current thread context

✨ SYNOPSIS ✨

#include <sys/param.h>
#include <sys/proc.h>

void
thread_exit(void);

💖 DESCRIPTION 💖

The thread_exit() function is literally the machine independent prelude to a thread shutdown. It will not return — no cap, it is not coming back — and it will result in a call to mi_switch(9) to schedule some other thread. 🫶

thread_exit() arranges to free all the resources of the thread, specifically the kernel stack. Like, it is handling the cleanup, bestie 🧹✨

To protect runqueue(9), thread_exit() must be called with the sched_lock mutex held. This is not optional — hold that mutex. 🔒💀

🔥 SEE ALSO 🔥

• mi_switch(9)
• mutex(9)
• runqueue(9)
• sleep(9)
