The Bison parser is actually a C function named yyparse
. Here we
describe the interface conventions of yyparse
and the other
functions that it needs to use.
Keep in mind that the parser uses many C identifiers starting with ‘yy’ and ‘YY’ for internal purposes. If you use such an identifier (aside from those in this manual) in an action or in epilogue in the grammar file, you are likely to run into trouble.
