  • 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>

      public int cb()
      Returns:
      the value of the cb field.

    • DeviceName

      public ByteBuffer DeviceName()
      Returns:
      a ByteBuffer view of the DeviceName field.

    • DeviceNameString

      public String DeviceNameString()
      Returns:
      the null-terminated string stored in the DeviceName field.

    • DeviceString

      public ByteBuffer DeviceString()
      Returns:
      a ByteBuffer view of the DeviceString field.

    • DeviceStringString

      public String DeviceStringString()
      Returns:
      the null-terminated string stored in the DeviceString field.

    • Flags

      Returns:
      the value of the Flags field.

    • rcVirtualScreen

      public RECT rcVirtualScreen()
      Returns:
      a RECT view of the rcVirtualScreen field.

    • malloc
