It is passing a variable. *Before* you parse it, you have to make it
inheritable by doing something along the line of:
DuplicateHandle(GetCurrentProcess(), GetCurrentProcess(),
GetCurrentProcess(), &targetHandle, 0, TRUE, DUPLICATE_SAME_ACCESS);

(If you just do GetCurrentProcess() it will return a hard-coded
pseudohandle. So if you use that handle in the child process, it will
point to the child process. DuplicateHandle will turn it into a real
handle)
