- <h3>Name</h3>
- userthreads - simple user-level threads test
- <h3>Synopsis</h3>
- /testbin/userthreads
- <h3>Description</h3>
- userthreads does simple console I/O from two threads in the same
- process.
- <h3>Requirements</h3>
- userthreads uses the following system calls:
- <ul>
- <li> <A HREF=../syscall/write.html>write</A>
- <li> <A HREF=../syscall/_exit.html>_exit</A>
- </ul>
- It also assumes the existence of a function threadfork(), which takes
- the address of a function to start a new thread at, and makes certain
- other assumptions about thread semantics. See the source file.
- <p>
- If implementing user-level threads, part of your responsibility is to
- update the userthreads test to work with the threads package you
- write.
