Very Computer

A beginner question:

How can i use the chdir() call in a program and have it affect
the current directory of the parent process?  Is there some
tricky way of telling the shell (csh in this case) to do a cd?

If this is a FAQ, i apologise.  Pointers to sources of
information about how a child process can affect the environment
of its parent would be very welcome.

Thanks

You can't. The parent process must execute a chdir(2) call itself.

You could tell the parent to the it's own chdir() but this requires
cooperation from the parent.

Look into the comp.unix.questions FAQ, it covers this topic at length.
