I would like to declare some variables that are local to yyparse. I
am building a linked list of structures, and I need to make sure I
have values for all the structure members before I add a new node to
the list. Since I wrote the parser to be a pure parser, global
variables, are not an option. Something like %initial-action {int x;
int y; int z;} doesn't work, since the initial action code is
enclosed in braces and the variables x,y,z,etc. do not exist outside
the braces. If I use %parse-param{variables_t variables;}, where
variables_t is a structure containing x,y,z, I get what I want, but
since I don't need x,y,z after yyparse returns, this seems like an
inefficient way to do things. Is there a better way to do this?
There must be a "standard" way this is done---temporarily saving all
the previously parsed values until all the required values are
available. Any help would be very appreciated. Thanks.
