Hi,
 
I want to use POSIX threads into my application which includes a scanner and a 
parser. I read that in that case I have to use re-entrant parser through 
%pure-parser directive.
 
I notice that I need to introduce some changes to my parser such as my yylex 
proto -> int yylex (YYSTYPE *lvalp, YYLTYPE *llocp). "yylval" is no longer 
useful, instead "lvalp" is used.
 
In my parser I used a %union directive, my question is: How can I use this 
union instead of "YYSTYPE *lvalp".
 
Thanks for any help.
 
Best regards,
AnL.
