---++ Meeting Discussion
   * DPI Review 
      * Need an extended example. 
         * Preferably from someone who did not write the proposal.
         * Could call something from one of the standard libraries.
      * Pointers? - VHDL cannot use the pointer, however, it can read it and pass the pointer to another C program. 
         * Create a pointer type.
      * Use C Interface to scripting languages, such as Perl, Python, ...
      * Can one call printf?
      * Passing strings to C and to scripting languages
      * [[https://sourceware.org/libffi/][LIBFFI]] - A Portable Foreign Function Interface Library
      * AI: Rob look into LIBFFI for VHDL
      * AI: Peter, example for either sockets or LIBFFI
      * How does the external library get bound to the simulator? Use VHDL's library syntax? 
         * ?DPI use logical library names?
   * Method to do introspection on names and find different objects 
      * find all instance labels whose component name is xyz.
   * Date and System Time Functions 
      * Rob and Morten
      * do separate vs. do with DPI?
      * Needs to be synthesizable.
   * String representation of values of composite types 
      * Discussion went in a different direction ...
      * Generalize s.t. a composite can implicitly call the conversion for the existing defined function (scalar)
      * type as a first class object?
      * reflection
      * AI: Lieven write proposal - perhaps after arbitrary integer.
