A question about error recovery

[zhke]

Hi there,

 

I have a question on memory recycling while handling parse errors.My situation is as below:

I defined the YYSTYPE as a pointer to a structure,something like

struct Object{

....

};

#define YYSTYPE Object*

 

I allocate memory for Objects in yylex(),and return the pointers as yylval.

Now if a parse error occurs,I want to abort from the yyparse() .How should I free memory of those objects remaining in the parse stack?Because my application is a deamon process,so the memory leaking is not endurable.

Could anybody give me any advice?Any reply would be appreciated.

 

Thanks,
