D12_BuildPipeList 一问

BuildPipeList 有何作用?
NTSTATUS
D12_BuildPipeList(
    IN  PDEVICE_OBJECT DeviceObject
    )
/*++

Routine Description:

Arguments:

    DeviceObject - pointer to the device object for this instance of the 82930
                    devcice.


Return Value:

    NT status code

--*/
{
    PDEVICE_EXTENSION deviceExtension;
    ULONG i;
    WCHAR Name[] = L\"\\\\PIPE00\";
    PUSBD_INTERFACE_INFORMATION interface;

    deviceExtension = DeviceObject->DeviceExtension;
    interface = deviceExtension->Interface;

    D12_KdPrint ((\"D12TEST.SYS: enter D12_BuildPipeList\\n\"));

    deviceExtension = DeviceObject->DeviceExtension;

    for (i=0; i<D12_MAX_PIPES; i++) {

        Name[6] = \'X\';//这个X在这里是什么意思
        RtlCopyMemory(deviceExtension->PipeList.Name,
                      Name,
                      sizeof(Name));


    }

BuildPipeList 有何作用?  //建立管道名字，可以让应用层调用
