Method Detail

• SetupDiGetClassDevs

  WinNT.HANDLE SetupDiGetClassDevs(Guid.GUID.ByReference classGuid,
                                 Pointer enumerator,
                                 Pointer hwndParent,
                                 int flags)

  The SetupDiGetClassDevs function returns a handle to a device information set that contains requested device information elements for a local computer.

  Parameters:

  classGuid - A pointer to the GUID for a device setup class or a device interface class. This pointer is optional and can be NULL. For more information about how to set ClassGuid, see the following Remarks section.

  enumerator - A pointer to a NULL-terminated string that specifies: An identifier (ID) of a Plug and Play (PnP) enumerator. This ID can either be the value's globally unique identifier (GUID) or symbolic name. For example, "PCI" can be used to specify the PCI PnP value. Other examples of symbolic names for PnP values include "USB," "PCMCIA," and "SCSI". A PnP device instance ID. When specifying a PnP device instance ID, DIGCF_DEVICEINTERFACE must be set in the Flags parameter. This pointer is optional and can be NULL. If an enumeration value is not used to select devices, set Enumerator to NULL.

  hwndParent - A handle to the top-level window to be used for a user interface that is associated with installing a device instance in the device information set. This handle is optional and can be NULL.

  flags - A variable of type DWORD that specifies control options that filter the device information elements that are added to the device information set.

  Returns:

  If the operation succeeds, SetupDiGetClassDevs returns a handle to a device information set that contains all installed devices that matched the supplied parameters. If the operation fails, the function returns INVALID_HANDLE_VALUE. To get extended error information, call GetLastError.

• SetupDiDestroyDeviceInfoList

  boolean SetupDiDestroyDeviceInfoList(WinNT.HANDLE hDevInfo)

  The SetupDiDestroyDeviceInfoList function deletes a device information set and frees all associated memory.

  Parameters:

  hDevInfo - A handle to the device information set to delete.

  Returns:

  The function returns TRUE if it is successful. Otherwise, it returns FALSE and the logged error can be retrieved with a call to GetLastError.

• SetupDiEnumDeviceInterfaces

  boolean SetupDiEnumDeviceInterfaces(WinNT.HANDLE hDevInfo,
                                    Pointer devInfo,
                                    Guid.GUID.ByReference interfaceClassGuid,
                                    int memberIndex,
                                    SetupApi.SP_DEVICE_INTERFACE_DATA.ByReference deviceInterfaceData)

  The SetupDiEnumDeviceInterfaces function enumerates the device interfaces that are contained in a device information set.

  Parameters:

  hDevInfo - A pointer to a device information set that contains the device interfaces for which to return information. This handle is typically returned by SetupDiGetClassDevs.

  devInfo - A pointer to an SP_DEVINFO_DATA structure that specifies a device information element in DeviceInfoSet. This parameter is optional and can be NULL. If this parameter is specified, SetupDiEnumDeviceInterfaces constrains the enumeration to the interfaces that are supported by the specified device. If this parameter is NULL, repeated calls to SetupDiEnumDeviceInterfaces return information about the interfaces that are associated with all the device information elements in DeviceInfoSet. This pointer is typically returned by SetupDiEnumDeviceInfo.

  interfaceClassGuid - A pointer to a GUID that specifies the device interface class for the requested interface.

  memberIndex - A zero-based index into the list of interfaces in the device information set. The caller should call this function first with MemberIndex set to zero to obtain the first interface. Then, repeatedly increment MemberIndex and retrieve an interface until this function fails and GetLastError returns ERROR_NO_MORE_ITEMS. If DeviceInfoData specifies a particular device, the MemberIndex is relative to only the interfaces exposed by that device.

  deviceInterfaceData - A pointer to a caller-allocated buffer that contains, on successful return, a completed SP_DEVICE_INTERFACE_DATA structure that identifies an interface that meets the search parameters. The caller must set DeviceInterfaceData.cbSize to sizeof(SP_DEVICE_INTERFACE_DATA) before calling this function.

  Returns:

  SetupDiEnumDeviceInterfaces returns TRUE if the function completed without error. If the function completed with an error, FALSE is returned and the error code for the failure can be retrieved by calling GetLastError.

• SetupDiGetDeviceInterfaceDetail

  boolean SetupDiGetDeviceInterfaceDetail(WinNT.HANDLE hDevInfo,
                                        SetupApi.SP_DEVICE_INTERFACE_DATA.ByReference deviceInterfaceData,
                                        Pointer deviceInterfaceDetailData,
                                        int deviceInterfaceDetailDataSize,
                                        IntByReference requiredSize,
                                        SetupApi.SP_DEVINFO_DATA.ByReference deviceInfoData)

  The SetupDiGetDeviceInterfaceDetail function returns details about a device interface.

  Parameters:

  hDevInfo - A pointer to the device information set that contains the interface for which to retrieve details. This handle is typically returned by SetupDiGetClassDevs.

  deviceInterfaceData - A pointer to an SP_DEVICE_INTERFACE_DATA structure that specifies the interface in DeviceInfoSet for which to retrieve details. A pointer of this type is typically returned by SetupDiEnumDeviceInterfaces.

  deviceInterfaceDetailData - A pointer to an SP_DEVICE_INTERFACE_DETAIL_DATA structure to receive information about the specified interface. This parameter is optional and can be NULL. This parameter must be NULL if DeviceInterfaceDetailSize is zero. If this parameter is specified, the caller must set DeviceInterfaceDetailData.cbSize to sizeof(SP_DEVICE_INTERFACE_DETAIL_DATA) before calling this function. The cbSize member always contains the size of the fixed part of the data structure, not a size reflecting the variable-length string at the end.

  deviceInterfaceDetailDataSize - The size of the DeviceInterfaceDetailData buffer. The buffer must be at least (offsetof(SP_DEVICE_INTERFACE_DETAIL_DATA, DevicePath) + sizeof(TCHAR)) bytes, to contain the fixed part of the structure and a single NULL to terminate an empty MULTI_SZ string. This parameter must be zero if DeviceInterfaceDetailData is NULL.

  requiredSize - A pointer to a variable of type DWORD that receives the required size of the DeviceInterfaceDetailData buffer. This size includes the size of the fixed part of the structure plus the number of bytes required for the variable-length device path string. This parameter is optional and can be NULL.

  deviceInfoData - A pointer to a buffer that receives information about the device that supports the requested interface. The caller must set DeviceInfoData.cbSize to sizeof(SP_DEVINFO_DATA). This parameter is optional and can be NULL.

  Returns:

  SetupDiGetDeviceInterfaceDetail returns TRUE if the function completed without error. If the function completed with an error, FALSE is returned and the error code for the failure can be retrieved by calling GetLastError.
