CeRegOpenKeyEx (RAPI) (Windows Embedded CE 6.0)

  • [アーティクル]

1/6/2010

This function opens the specified registry key on a remote Windows Embedded CE–based device.

Syntax

LONG CeRegOpenKeyEx( 
  HKEY hKey, 
  LPCWSTR lpszSubKey, 
  DWORD ulOptions, 
  REGSAM samDesired, 
  PHKEY phkResult 
);

Parameters

  • hKey
    [in] Handle to a currently 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 HKEY_CURRENT_CONFIG, HKEY_PERFORMANCE_DATA, or HKEY_DYN_DATA predefined reserved handle values.

  • lpszSubKey
    [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 will open a new handle to the key identified by the hKey parameter. In this case, the function will not close the handles previously opened.
  • ulOptions
    [in] Reserved; set to 0.
  • samDesired
    [in] Not supported; set to zero.
  • phkResult
    [out] Pointer to a variable that receives a handle to the opened key. When you no longer need the returned handle, call the CeRegCloseKey function to close it.

Return Value

ERROR_SUCCESS indicates success. A nonzero error code defined in Winerror.h indicates failure. To get a generic description of the error, call FormatMessage with the FORMAT_MESSAGE_FROM_SYSTEM flag set.

Remarks

Unlike the CeRegCreateKeyEx function, the CeRegOpenKeyEx function does not create the specified key if the key does not exist in the registry.

Requirements

Header rapi.h
Library rapi.lib
Windows Embedded CE Windows CE 3.0 and later
