# thread\_exit(9)

abandon current thread context

## 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 implements the machine independent prelude to a thread shutdown. It will not return, and will result in a call to [mi\_switch(9)](/mi_switch/9.md) to schedule some other thread.

**thread\_exit**() arranges to free all the resources of the thread, specifically the kernel stack.

To protect the [runqueue(9)](/runqueue/9.md), **thread\_exit**() must be called with the *sched\_lock* mutex held.

## SEE ALSO
