Although I'm not familiar with the context for this code, I have
a little comment...

You may be able to use GetProcessTimes on the process handle
to determine the creation time of the particular process. If it
is older than the time at which the parent spawned child
processes, then even though it might appear to be a child it almost
certainly isn't. Conversely if the creation time is after, then
you can almost certainly say it is a child process.

(Note that even this isn't perfect, since the system clock can
be changed, but it's probably more reliable.)

Cheers,
