MFC related differences between NT & 95/98

BOOL CreateDirectory(
  LPCTSTR lpPathName,                         // pointer to directory path string
  LPSECURITY_ATTRIBUTES lpSecurityAttributes  // pointer to security descriptor
);

95/98 can't use security attributes in creating files/directories.  There's several functions in this category

LONG RegCreateKeyEx(
  HKEY hKey,                // handle to an open key
  LPCTSTR lpSubKey,         // address of subkey name
  DWORD Reserved,           // reserved
  LPTSTR lpClass,           // address of class string
  DWORD dwOptions,          // special options flag
  REGSAM samDesired,        // desired security access
  LPSECURITY_ATTRIBUTES lpSecurityAttributes,
                            // address of key security structure
  PHKEY phkResult,          // address of buffer for opened handle
  LPDWORD lpdwDisposition   // address of disposition value buffer
);
 
Ten different registry functions can have security attributes as well, but not in 98.

SetGraphicsMode & SetWorldTransformation are only available in WinNT.

AlphaBlend/TransparentBlt are NT and 98 but not 95.

The PlgBlt/MaskBlt functions are only for WinNT.
