    • Field Detail

      • SIZEOF

        The struct size in bytes.

      • ALIGNOF

        The struct alignment in bytes.

      • CB, DEVICENAME, DEVICESTRING, FLAGS, RCVIRTUALSCREEN

        The struct member offsets.

    • Constructor Detail

      • GPU_DEVICE

        public GPU_DEVICE​(java.nio.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 Detail

      • sizeof

        public int sizeof()
        Specified by:
        sizeof in class org.lwjgl.system.Struct

      • 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, DeviceNameString

        public java.nio.ByteBuffer DeviceName()

public java.lang.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, DeviceStringString

        public java.nio.ByteBuffer DeviceString()

public java.lang.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 org.lwjgl.system.windows.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.
