    • Constructor Detail

      • CLDeviceTopologyAMD

        public CLDeviceTopologyAMD​(java.nio.ByteBuffer container)
        Creates a CLDeviceTopologyAMD 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

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

        public int raw_data​(int index)
        Returns:
        the value at the specified index of the raw.data field.

      • pcie_type

        public int pcie_type()
        Returns:
        the value of the pcie.type field.

        the value of the pcie.bus field.

      • pcie_device

        public byte pcie_device()
        Returns:
        the value of the pcie.device field.

      • pcie_function

        public byte pcie_function()
        Returns:
        the value of the pcie.function field.

      • malloc

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

      • calloc

        public static CLDeviceTopologyAMD calloc()
        Returns a new CLDeviceTopologyAMD instance allocated with memCalloc. The instance must be explicitly freed.

      • create

        public static CLDeviceTopologyAMD create()
        Returns a new CLDeviceTopologyAMD instance allocated with BufferUtils.

      • create

        public static CLDeviceTopologyAMD create​(long address)
        Returns a new CLDeviceTopologyAMD instance for the specified memory address.

      • createSafe

        @Nullable
public static CLDeviceTopologyAMD createSafe​(long address)
        Like create, but returns null if address is NULL.
