/*
* IoGetDeviceInterfaces
*
* Returns a list of device interfaces of a particular device interface class.
*
* Parameters
* InterfaceClassGuid
* Points to a class GUID specifying the device interface class.
*
* PhysicalDeviceObject
* Points to an optional PDO that narrows the search to only the
* device interfaces of the device represented by the PDO.
*
* Flags
* Specifies flags that modify the search for device interfaces. The
* DEVICE_INTERFACE_INCLUDE_NONACTIVE flag specifies that the list of
* returned symbolic links should contain also disabled device
* interfaces in addition to the enabled ones.
*
* SymbolicLinkList
* Points to a character pointer that is filled in on successful return
* with a list of unicode strings identifying the device interfaces
* that match the search criteria. The newly allocated buffer contains
* a list of symbolic link names. Each unicode string in the list is
* null-terminated; the end of the whole list is marked by an additional
* NULL. The caller is responsible for freeing the buffer (ExFreePool)
* when it is no longer needed.
* If no device interfaces match the search criteria, this routine
* returns STATUS_SUCCESS and the string contains a single NULL
* character.
*
* Status
* @unimplemented
*
* The parameters PhysicalDeviceObject and Flags aren't correctly
* processed. Rest of the cases was tested under Win XP and the
* function worked correctly.
