Allow a user specified parameter to 'yyparse()', in a manner similar to
...
that used by bison. The names are consistent with the bison implementation
but this one also allows the type of the parameter to be specified.
For a desired prototype of:
int yyparse __P((struct yyresult *));
and compile like this:
yacc -dv grammar.y
cc -c -DYYPARSE_PARAM_TYPE="struct yyresult *" \
-DYYPARSE_PARAM="parm" y.tab.c
and use like this:
${
#include "usrtypes.h"
#include "usrproto.h"
}$
%token NUMBER
%%
goal : NUMBER
{
parm->value = yylval;
} ;
If YYPARSE_PARAM_TYPE isn't specified then "void *" is the default type.
If YYPARSE_PARAM is not specified then the generated code behaves exactly
as traditional byacc.
