Hi Hans,
I 've already read this section but still the problem remains. It is ok
about the arguments however it does not provide a way to rename the yylex
function . I did also a little search of my own throughout the web and i got
more confused . From what i've read about the topic it seems that such thing
isn't possible due to preserving the namespace which you mentioned earlier.
So it is time for plan B i.e. move the functionality from the wrapper
function to yylex .Thanx once again Hans
