    Register to the parent via the child and pass the pid of the child to the parent.

    The 'ps' command seems to know a lot about the parent/child relationship of all processes.

    Perhaps study the source code of that?
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
