@subheading Description

This function places the specified function @var{func} on a list of
functions to be called when @code{exit} is called.  These functions are
called as if a last-in-first-out queue is used, that is, the last
function registered with @code{atexit} will be the first function called
by @code{exit}.

At least 32 functions can be registered this way.

@subheading Return Value

Zero on success, non-zero on error.

@example
void exit_func()
@{
  remove("file.tmp");
