函數原型

1 LONG RegCreateKeyEx(2 HKEY hKey, // handle to open key3 LPCTSTR lpSubKey, // subkey name4 DWORD Reserved, // reserved5 LPTSTR lpClass, // class string6 DWORD dwOptions, // special options7 REGSAM samDesired, // desired security access8 LPSECURITY_ATTRIBUTES lpSecurityAttributes, // inheritance9 PHKEY phkResult, // key handle 10 LPDWORD lpdwDisposition // disposition value buffer 11 );

參數說明
