Routine Description:

   This is the standard DLL entrypoint routine, called whenever a process
   or thread attaches or detaches.
   Arguments:

   hModule -   PVOID parameter that specifies the handle of the DLL

   Reason -    ULONG parameter that specifies the reason this entrypoint
               was called (either PROCESS_ATTACH, PROCESS_DETACH,
               THREAD_ATTACH, or THREAD_DETACH).

   pContext -  ???

Return value:

   Returns true if initialization compeleted successfully, false is not.
