        YY_FATAL_ERROR( "input in flex scanner failed" );

Definition at line 679 of file XdlScanner.cpp.

#define YY_NO_UNISTD_H

Disable the inclusion of unistd.h, which is not available under Visual C++ on Win32.

The C++ scanner uses STL streams instead.

    }

Definition at line 283 of file XdlScanner.cpp.

#define YY_USER_ACTION   yylloc->columns(yyleng);

Enable C++ generation for the scanner class.

Change the name of the scanner class to "XdlFlexLexer". The manual says batch is "somewhat more optimized". Enable debug output from the scanner. We anticipate no included XDL files. Enable the use of start condition stacks. Track location information. Each time yylex is invoked, begin is moved to end.

Definition at line 627 of file XdlScanner.cpp.

 

#define yyterminate

(

)

return token::END

By default, yylex() returns int, but we want token_type instead. Unfortunately, yyterminate returns 0 by default, which is not of token_type.
