open_memory_file(+Handle, +Mode, -Stream)

Open the memory-file. Mode is one of read, write, append, update or insert. The resulting Stream must be closed using close/1. When opened for update or insert, the current location is initialized at the start of the data and can be modified using seek/4 or set_stream_position/2. In update mode, existing content is replaced, while the size is enlarged after hitting the end of the data. In insert mode, the new data is inserted at the current point.
