This function opens the specified key.

Syntax

LONG NKRegOpenKeyEx(
  HKEY hKey, 
  LPCWSTR lpSubKey, 
  DWORD ulOptions, 
  REGSAM samDesired, 
  PHKEY phkResult
);

Parameters

  • hKey
    [in] Handle to an open key or any of the following predefined reserved handle values:

    • HKEY_CLASSES_ROOT
    • HKEY_CURRENT_USER
    • HKEY_LOCAL_MACHINE
    • HKEY_USERS

    Windows Embedded CE does not support the following predefined reserved handle values:

    • HKEY_CURRENT_CONFIG
    • HKEY_PERFORMANCE_DATA
    • HKEY_DYN_DATA.

  • lpSubKey
    [in] Pointer to a null-terminated string containing the name of the subkey to open.

    If this parameter is NULL or a pointer to an empty string, the function opens a new handle to the key identified by the hKey parameter. In this case, the function does not close the handles previously opened.

  • ulOptions
    [in] Reserved; set to 0.
  • samDesired
    [in] Not supported; set to 0.

  • phkResult
    [out] Pointer to a variable that receives a handle to the opened key.

    When you no longer need the returned handle, call the NKRegCloseKey function to close it.

Return Value

ERROR_SUCCESS indicates success.

A nonzero error code defined in Winerror.h indicates failure.

Remarks

This function is only available for use by the OAL.
