   placeholder symbol. To keep code size at a minimum, it is declared
   without a return value or parameters. The caller will still clean up 
   the stack frame correctly. 

   When using the _H_USER stream, the function will be implemented in
   application code with the prototype:   
    int _user_putc (char c);
