You must sent the pointer to the other processes somehow. Writing it to
a region of shared memory allocated prior to pfConfig is the common
approach. The *original* address will be shared because it was written
before the fork and copied, so that shared memory area can be used to
pass other pointers which will then be available for other processes to
read.

Cheers,ANgus.
