      void run(@Nullable byte @Nullable [] pixels)

      A function of this type is responsible for freeing the pixel array of a pixbuf.

      The gdk_pixbuf_new_from_data() function lets you pass in a pre-allocated pixel array so that a pixbuf can be created from it; in this case you will need to pass in a function of type GdkPixbufDestroyNotify so that the pixel data can be freed when the pixbuf is finalized.

      Parameters:
      pixels - The pixel array of the pixbuf that is being finalized.

    • upcall

      default void upcall(MemorySegment pixels, MemorySegment data)
      The upcall method is called from native code. The parameters are marshaled and run(byte[]) is executed.

    • toCallback

      default MemorySegment toCallback(Arena arena)
      Creates a native function pointer to the upcall(MemorySegment, MemorySegment) method.
      Specified by:
      toCallback in interface FunctionPointer
      Parameters:
      arena - the arena in which the function pointer is allocated
      Returns:
