fork, execv & state variables

| Using C++ on FC4, if in a class method, do I do a
fork(), do the resulting two processes have separate
sets of object state variables?
Thanks for your help.
Mike.

fork creates a child process that differs from the parent process only
in its PID and PPID, and in the fact that resource utilizations are set
to 0. File locks and pending signals are not inherited.

I believe this implies that the processes "have separate sets of object
state variables".

This newsgroup only deals with standard C++, not platform specific
features. See
http://www.parashift.com/c++-faq-li...st.html#faq-5.9 for
newsgroup suggestions.

I didn't notice the crosspost to linux.redhat.misc, my message only
applies to comp.lang.c++. To the OP: crossposting is seldom a good
idea.
Followup set to l.r.m.
