A new Lexer ist just a new object. FlexLexer::yyrestart accepts an input stream like std::stringstream. i do not know how it is done in C. For different Lexer you can specify an Prefix like %option prefix="CMD" and it generates a class CMDFlexLexer. bison is only C and you have to write an wrapper if you want an object. But there is also an option %name-prefix="cmd" which gives generated functions that prefix. This options are described in some documentation but maybe it is hard to find. It is an ode solver with a simple command line. Sorry, my english is not very well. I worked with flex and bison recently (many years ago) too. flex could generate a c++ class if you want.
