//
// Generic Callbacks.
//
// WOWCallback16 can be used in Win32 code called
// from 16-bit (such as by using Generic Thunks) to call back to
// the 16-bit side.  The function called must be declared similarly
// to the following:
//
// LONG FAR PASCAL CallbackRoutine(DWORD dwParam);
//
// If you are passing a pointer, declare the parameter as such:
//
// LONG FAR PASCAL CallbackRoutine(VOID FAR *vp);
//
// NOTE: If you are passing a pointer, you'll need to get the
// pointer using WOWGlobalAlloc16 or WOWGlobalAllocLock16
//
// If the function called returns a WORD instead of a DWORD, the
// upper 16 bits of the return value is undefined.  Similarly, if
// the function called has no return value, the entire return value
// is undefined.
//
// WOWCallback16Ex allows any combination of arguments up to
// WCB16_MAX_CBARGS bytes total to be passed to the 16-bit routine.
// cbArgs is used to properly clean up the 16-bit stack after calling
// the routine.  Regardless of the value of cbArgs, WCB16_MAX_CBARGS
// bytes will always be copied from pArgs to the 16-bit stack.  If
// pArgs is less than WCB16_MAX_CBARGS bytes from the end of a page,
// and the next page is inaccessible, WOWCallback16Ex will incur an
// access violation.
//
// If cbArgs is larger than the WCB16_MAX_ARGS which the running
// system supports, the function returns FALSE and GetLastError
// returns ERROR_INVALID_PARAMETER.  Otherwise the function
// returns TRUE and the DWORD pointed to by pdwRetCode contains
// the return code from the callback routine.  If the callback
// routine returns a WORD, the HIWORD of the return code is
// undefined and should be ignored using LOWORD(dwRetCode).
//
// WOWCallback16Ex can call routines using the PASCAL and CDECL
// calling conventions.  The default is to use the PASCAL
// calling convention.  To use CDECL, pass WCB16_CDECL in the
// dwFlags parameter.
//
// The arguments pointed to by pArgs must be in the correct
// order for the callback routine's calling convention.
// To call the PASCAL routine SetWindowText,
//
// LONG FAR PASCAL SetWindowText(HWND hwnd, LPCSTR lpsz);
//
// pArgs would point to an array of words:
//
// WORD SetWindowTextArgs[] = {OFFSETOF(lpsz), SELECTOROF(lpsz), hwnd};
//
// In other words, the arguments are placed in the array in reverse
// order with the least significant word first for DWORDs and offset
// first for FAR pointers.
//
// To call the CDECL routine wsprintf, for example
//
// LPSTR lpszFormat = "%d %s";
// int _cdecl wsprintf(lpsz, lpszFormat, nValue. lpszString);
//
// pArgs would point to the array:
//
// WORD wsprintfArgs[] = {OFFSETOF(lpsz), SELECTOROF(lpsz),
//                        OFFSETOF(lpszFormat), SELECTOROF(lpszFormat),
//                        nValue,
//                        OFFSETOF(lpszString), SELECTOROF(lpszString)};
//
// In other words, the arguments are placed in the array in the order
// listed in the function prototype with the least significant word
// first for DWORDs and offset first for FAR pointers.
