4.3 The Pull Parser Function yypull_parse

(The current push parsing interface is experimental and may evolve. More user feedback will help to stabilize it.)

You call the function yypull_parse to parse the rest of the input stream. This function is available if the %define api.push_pull "both" declaration is used. See section A Push Parser.

Function: int yypull_parse (yypstate *yyps)

The value returned by yypull_parse is the same as for yyparse.
