That's interesting since Windows doesn't have process groups. I wonder what it actually does ( when asked to kill a process group ).

    Corion recently told me that "under the Windows fork emulation, emulated forked children get negative PIDs". I don't know where this is documented but I believe him.

      That's true, but I don't see how it's relevant. He's passing a negative signal.

        My mistake, I thought you were asking about the other "it".

    See kill_process_tree_toolhelp() in win32.c
