Re: accessing yyval outside lex and yacc

[Akim Demaille]

| A good approximation simply consists in a wrapper around yyparse, in
| the preamble, or the postamble of your .y:
| 
| Constraint *
| constraint_parse ()

constraint_parse (const char *filename)


| {
|   Constraint *res = 0
|   // Set up yyin
|   if (yyparse ())
|     return root;
|   else
|     return NULL;
| }
| 
| and keep root static.
