  • Constructor Details

    • GPU_DEVICE

      public GPU_DEVICE(ByteBuffer container)
      Creates a GPU_DEVICE instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

      The created instance holds a strong reference to the container object.

  • Method Details

    • sizeof

      public int sizeof()
      Description copied from class: Struct
      Returns sizeof(struct).
      Specified by:
      sizeof in class Struct<GPU_DEVICE>

    • cb

      public int cb()
      the size of the GPU_DEVICE structure. Before calling EnumGpuDevicesNV, set cb to the size, in bytes, of GPU_DEVICE.

    • DeviceName

      public ByteBuffer DeviceName()
      a string identifying the display device name. This will be the same string as stored in the DeviceName field of the DISPLAY_DEVICE structure, which is filled in by EnumDisplayDevices.

    • DeviceNameString

      public String DeviceNameString()
      a string identifying the display device name. This will be the same string as stored in the DeviceName field of the DISPLAY_DEVICE structure, which is filled in by EnumDisplayDevices.

    • DeviceString

      public ByteBuffer DeviceString()
      a string describing the GPU for this display device. It is the same string as stored in the DeviceString field in the DISPLAY_DEVICE structure that is filled in by EnumDisplayDevices when it describes a display adapter (and not a monitor).

    • DeviceStringString

      public String DeviceStringString()
      a string describing the GPU for this display device. It is the same string as stored in the DeviceString field in the DISPLAY_DEVICE structure that is filled in by EnumDisplayDevices when it describes a display adapter (and not a monitor).

    • Flags

      public int Flags()
      indicates the state of the display device

    • rcVirtualScreen

      public RECT rcVirtualScreen()
      specifies the display device rectangle, in virtual screen coordinates. The value of rcVirtualScreen is undefined if the device is not part of the desktop, i.e. DISPLAY_DEVICE_ATTACHED_TO_DESKTOP is not set in the Flags field.

    • malloc

      public static GPU_DEVICE malloc()
      Returns a new GPU_DEVICE instance allocated with memAlloc. The instance must be explicitly freed.

    • createSafe

      @Nullable public static GPU_DEVICE createSafe(long address)

    • malloc

      public static GPU_DEVICE.Buffer malloc(int capacity)
      Returns a new GPU_DEVICE.Buffer instance allocated with memAlloc. The instance must be explicitly freed.
      Parameters:
      capacity - the buffer capacity

    • calloc

      public static GPU_DEVICE.Buffer calloc(int capacity)
