Passing filled AST to yyparse() caller after successful parse

[Jeannot Langlois]

Hi all,

In a reentrant GLR parser, how must the yyparse() caller proceed to access the filled AST after a successful parse?  I was expecting yyparse() to return a pointer (whose type could be custom-defined by the user just like the yylex() and yyparse() input parameters) to the properly-filled AST, but it seems that this is not the case and the yyparse() return value is only used to return a parse status code.

Any ideas or documentation pointers about that?

Thanks in advance,
