exename
  The fully qualified name of the executable that has trapped
PID
  The process ID of the executable that has trapped

Ordinal 2:

    void _System enddump(unsigned long PID);

This function, if you provide it, is called at the end of the process dump. Use it to add additional process logging and control. The function parameter, PID, is the process ID of the executable that has trapped.
