yypush_parse
(The current push parsing interface is experimental and may evolve. More user feedback will help to stabilize it.)
You call the function yypush_parse
to parse a single token. This
function is available if either the ‘%define api.push-pull push’ or
‘%define api.push-pull both’ declaration is used.
See A Push Parser.
The value returned by yypush_parse
is the same as for yyparse with
the following exception: it returns YYPUSH_MORE
if more input is
required to finish parsing the grammar.
