clone() documentation

[scorpio2002]

Hi there! Do you know where I can find good documentation about the syscall clone()? I need a lot of examples and code... thx

# apt-get install manpages-dev
# man 2 clone

oh yeah, you're right... but manpages are very far from myconcept of good documentation :-)
I need help on how to create the stack area. The man pages don't say anything about that:

The child_stack argument specifies the location of the stack used by
the child process. Since the child and calling process may share mem‐
ory, it is not possible for the child process to execute in the same
stack as the calling process. The calling process must therefore set
up memory space for the child stack and pass a pointer to this space to
clone. Stacks grow downwards on all processors that run Linux (except
the HP PA processors), so child_stack usually points to the topmost
address of the memory space set up for the child stack.

so far so good. But it should've gone on explaining how to create that stack :| Shall I use malloc? plz help :-) I'd like an example, I can't find any on the web...
