No, it was attached to the mail. Will commit though.

What I read was:
"The thread exits (that is, calls/pthread_exit/()
<http://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_exit.html>)."
Then I clicked the
link(http://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_exit.html
<http://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_exit.html>),
hoping to find this:
"An implicit call to/pthread_exit/() is made when a thread other than
the thread in which/main/() was first invoked returns from the start
routine that was used to create it."
And when I did, I've overlooked '{', expecting an '}'. I regard this as
slight inconsistency in the standard. At least it's missing the word
"explicitly", but I'd reword it altogether hehe.
Anyway, I'll just cast the void* to a function pointer and call it directly.
Thanks.
Luka
