CM_Get_Version_Ex function (cfgmgr32.h)

[Beginning with Windows 8 and Windows Server 2012, this function has been deprecated and should not be used.]

The CM_Get_Version_Ex function returns version 4.0 of the Plug and Play (PnP) Configuration Manager DLL (Cfgmgr32.dll) for a local or a remote machine.

Syntax

CMAPI WORD CM_Get_Version_Ex(
  [in, optional] HMACHINE hMachine
);

Parameters

[in, optional] hMachine

Supplies a machine handle that is returned by CM_Connect_Machine.

Return value

If the function succeeds, it returns the major revision number in the high-order byte and the minor revision number in the low-order byte. Version 4.0 is returned as 0x0400. By default, version 4.0 is supported by Microsoft Windows 2000 and later versions of Windows. If an internal error occurs, the function returns 0x0000. Call GetLastError to obtain the error code for the failure.

Remarks

This function returns version 4.0 of the configuration manager to ensure compatibility with version 4.0 and all later versions of the configuration manager, and to ensure compatibility with all applications that require version 4.0 of the configuration manager.

To determine if a specific version of the configuration manager is available on a machine, use CM_Is_Version_Available or CM_Is_Version_Available_Ex.

Functionality to access remote machines has been removed in Windows 8 and Windows Server 2012 and later operating systems thus you cannot access remote machines when running on these versions of Windows.
