[FleXML-Users] generated parser declaration

[Dowling, W. (W. (TS USA) <wil...@th...>]

One limitation of the flexml-generated parser is that its prototype is
fixed within flexml:
  int yylex()
In order to pass in a parameter to the generated parser, I had to resort
to a flex command line that contained this (I am generating C++ code,
hence the class declaration)

-PLinksXML \
-DYY_DECL='"class LinksAPIStart; static LinksAPIStart *
private_Start_ptr; int LinksXMLlex(LinksAPIStart *LinksAPIStart_ptr)"' \
-DYY_USER_INIT='"private_Start_ptr=LinksAPIStart_ptr;"'

This trick allows me to refer to the parameter passed into the parser
(LinksAPIStart_ptr) using the name private_Start_ptr in my .act file.

I sure would like a cleaner way to do this.  Any ideas?

Will
