      • CLBusAddressAMD

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

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

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

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

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