    • read – fill data with size bytes. Return number of bytes actually read.
    • skip – skip the next n bytes, or unget the last -n bytes if negative
    • eof – returns nonzero if we are at end of file/data

      • STBIIOCallbacks

        public STBIIOCallbacks(java.nio.ByteBuffer container)
        Creates a STBIIOCallbacks 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.
