CM_Is_Version_Available_Ex function

The CM_Is_Version_Available_Ex function indicates whether a specified version of the Plug and Play (PNP) Configuration Manager DLL (Cfgmgr32.dll) is supported by a local or a remote machine.

Syntax


CMAPI
BOOL
WINAPI CM_Is_Version_Available_Ex(
  _In_      WORD wVersion,
  _In_opt_  HMACHINE hMachine
);

Parameters

wVersion [in]

Identifies a version of the configuration manager. The supported version of the configuration manager corresponds directly to the operating system version. The major version is specified by the high-order byte and the minor version is specified by the low-order byte. For example, 0x0400 specifies version 4.0, which is supported by default by Microsoft Windows NT 4.0 and later versions of Windows. Version 0x0501 specifies version 5.1, which is supported by Windows XP and later versions of Windows.

hMachine [in, optional]

Supplies a machine handle that is returned by CM_Connect_Machine.

Note  Using this function to access remote machines is not supported beginning with Windows 8 and Windows Server 2012, as this functionality has been removed.

Return value

The function returns TRUE if the function can connect to the specified machine and if the machine supports the specified version. Otherwise, the function returns FALSE.

Remarks

Use this function to determine whether a specified version of the configuration manager is supported by a local or a remote machine. If the specified version is supported, all versions earlier and including this version are supported by the machine. You can also use CM_Is_Version_Available to determine if the local machine supports a specific version of the configuration manager.

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.

Available in Windows XP and later versions of Windows.
