CeRegOpenKeyEx (RAPI)

Send Feedback

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

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 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 Values

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

Pocket PC: Pocket PC 2002 and later
