//         ...,
//         argN,
//

//
//         0x???,       // Bit mask indicating which args are pointers
//                      //   that need to be mapped from a 16:16 address
//                      //   to a 0:32 address. The least significant
//                      //   bit corresponds to argN, and the Nth bit
//                      //   corresponds to arg1.
//                      //
//                      //   For example, if arg1 & arg2 are pointers, and
//                      //   arg3 is a DWORD, the the mask would be 0x6
//                      //   (110 in binary, indicating arg1 & arg2 need to
//                      //   be mapped)
//
//         N            // Number of TAPI proc args
//         );
//
//
// Since callbacks to 16-bit procs cannot be done directly by a 32-bit
// module, we create a hidden window for each successful call to
// lineInitialize and phoneInitialize, and tapi32.dll posts msgs to this
// window when LINE_XXX & PHONE_XXX msgs become available for the client
// process. The window then retrieves all the msgs parameters and calls
// the 16-bit proc's callback function.
//
// Note that we swap the hLineApp & hPhoneApp returned by tapi32.dll with
// the hidden window handle on the client proc side, and substitute the
// window handle for the pointer to the callback function on the tapi32.dll
// side. The former is done to make it easier to reference which window
// belongs to which hLine/PhoneApp, and the latter is done to provide
// tapi32.dll with a means of alerting us of callback msgs. (Tapi32.dll
// distinguishes whether the lpfnCallback it is passed in
// line/phoneInitialize is a pointer to a function of a window handle by
// checking the high WORD- if it is 0xffff then it assumes lpfnCallback
// is really a 16-bit proc's window handle.
