Use these:

LONG RegOpenKey(
HKEY hKey, // handle to open key
LPCTSTR lpSubKey, // name of subkey to open
PHKEY phkResult // handle to open key
);

LONG RegSetValueEx(
HKEY hKey, // handle to key
LPCTSTR lpValueName, // value name
DWORD Reserved, // reserved
DWORD dwType, // value type
CONST BYTE *lpData, // value data
DWORD cbData // size of value data
);

LONG RegCloseKey(
HKEY hKey // handle to key to close
);

For more info, go to msdn.microsoft.com and use the search function.
