CeRegCloseKey

  • Article

This function releases the handle of the specified key. CeRegCloseKey is a RAPI that enables an application that is running on a desktop computer to make function calls on a Microsoft® Windows® CE–based device.

STDAPI_(LONG) CeRegCloseKey(
  HKEY hKey 
);

Parameters

  • hKey
    [in] Handle to the open key to close.

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

The handle for a specified key should not be used after it has been closed, because it will no longer be valid. Key handles should not be left open any longer than necessary.

The CeRegCloseKey function always writes information to the registry before returning, eliminating the need to flush keys in the Windows CE registry.

Requirements

Smartphone Platforms: Smartphone 2002 and later
OS Versions: Windows CE 3.0 and later
Header: rapi.h
Library: rapi.lib
