/*
|
|
* 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.
