CM_Get_Device_ID_List_ExA function (cfgmgr32.h)

  • Article

[Beginning with Windows 8 and Windows Server 2012, this function has been deprecated. Please use CM_Get_Device_ID_List instead.]

The CM_Get_Device_ID_List_Ex function retrieves a list of device instance IDs for the device instances on a local or a remote machine.

Syntax

CMAPI CONFIGRET CM_Get_Device_ID_List_ExA(
  [in, optional] PCSTR    pszFilter,
  [out]          PZZSTR   Buffer,
  [in]           ULONG    BufferLen,
  [in]           ULONG    ulFlags,
  [in, optional] HMACHINE hMachine
);

Parameters

[in, optional] pszFilter

Caller-supplied pointer to a character string specifying a subset of the machine's device instance identifiers, or NULL. See the following description of ulFlags.

[out] Buffer

Address of a buffer to receive a set of NULL-terminated device instance identifier strings. The end of the set is terminated by an extra NULL. The required buffer size should be obtained by calling CM_Get_Device_ID_List_Size_Ex.

[in] BufferLen

Caller-supplied length, in characters, of the buffer specified by Buffer.

[in] ulFlags

One of the optional, caller-supplied bit flags that specify search filters. If no flags are specified, the function supplies all instance identifiers for all device instances. For a list of bit flags, see the ulFlags description for CM_Get_Device_ID_List.

[in, optional] hMachine

Caller-supplied machine handle, obtained from a previous call to 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

If the operation succeeds, the function returns CR_SUCCESS. Otherwise, it returns one of the CR_-prefixed error codes defined in Cfgmgr32.h.

Remarks

For information about device instance IDs, see Device Identification Strings.

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.
