RegCreateKey info  Overview  Group

The RegCreateKey function creates the specified key. If the key already exists in the registry, the function opens it. This function is provided for compatibility with Windows version 3.1. Win32-based applications should use the RegCreateKeyEx function.

LONG RegCreateKey(

    HKEY hKey,

// handle of an open key

    LPCTSTR lpSubKey,

// address of name of subkey to open

    PHKEY phkResult 

// address of buffer for opened handle

   );

Parameters

hKey
Identifies a currently open key or one of the following predefined reserved handle values:

HKEY_CLASSES_ROOT
HKEY_CURRENT_CONFIG
HKEY_CURRENT_USER
HKEY_LOCAL_MACHINE
HKEY_USERS
Windows NT only: HKEY_PERFORMANCE_DATA 
Windows 95 only: HKEY_DYN_DATA 

The key opened or created by the RegCreateKey function is a subkey of the key identified by hKey.

lpSubKey
Points to a null-terminated string specifying the name of a key that this function opens or creates. This key must be a subkey of the key identified by the hKey parameter.

If hKey is one of the predefined keys, lpSubKey may be NULL. In that case, the handle returned by using phkResult is the same hKey handle passed in to the function.

phkResult
Points to a variable that receives the handle of the opened or created key.

Return Values

If the function succeeds, the return value is ERROR_SUCCESS.

If the function fails, the return value is a nonzero error code defined in WINERROR.H. You can use the FormatMessage function with the FORMAT_MESSAGE_FROM_SYSTEM flag to get a generic description of the error.

Remarks

An application can use the RegCreateKey function to create several keys at once. For example, an application can create a subkey four levels deep at the same time as the three preceding subkeys by specifying a string of the following form for the lpSubKey parameter:

subkey1\subkey2\subkey3\subkey4

The key identified by the hKey parameter must have been opened with KEY_CREATE_SUB_KEY access (KEY_WRITE access includes KEY_CREATE_SUB_KEY access).

If the lpSubKey parameter is the address of an empty string, the function opens and then passes back the key identified by the hKey parameter.
