CeRegOpenKeyEx (RAPI) (Windows Embedded CE 6.0)
1/6/2010
This function opens the specified registry key on a remote Windows Embedded CEābased 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.
