CM_Get_Res_Des_Data_Ex function

The CM_Get_Res_Des_Data_Ex function retrieves the information stored in a resource descriptor on a local or a remote machine.

Syntax


CMAPI
CONFIGRET
WINAPI CM_Get_Res_Des_Data_Ex(
  _In_     RES_DES  rdResDes,
  _Out_    PVOID    Buffer,
  _In_     ULONG    BufferLen,
  _In_     ULONG    ulFlags,
  _In_opt_ HMACHINE hMachine
);

Parameters

rdResDes [in]

Caller-supplied handle to a resource descriptor, obtained by a previous call to CM_Get_Next_Res_Des_Ex.

Buffer [out]

Address of a buffer to receive the contents of a resource descriptor. The required buffer size should be obtained by calling CM_Get_Res_Des_Data_Size_Ex.

BufferLen [in]

Caller-supplied length of the buffer specified by Buffer.

ulFlags [in]

Not used, must be zero.

hMachine [in, optional]

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.

Note  Starting with Windows 8, CM_Get_Res_Des_Data_Ex returns CR_CALL_NOT_IMPLEMENTED when used in a Wow64 scenario. To request information about the hardware resources on a local machine it is necessary implement an architecture-native version of the application using the hardware resource APIs. For example: An AMD64 application for AMD64 systems.

Remarks

Information returned in the buffer supplied by Buffer will be formatted as one of the resource type structures listed in the description of CM_Add_Res_Des_Ex, based on the resource type that was specified when CM_Get_Next_Res_Des_Ex was called to obtain the resource descriptor handle.

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.
