The Lexical Analyzer Function `yylex' ===================================== The "lexical analyzer" function, `yylex', recognizes tokens from the input stream and returns them to the parser. Bison does not create this function automatically; you must write it so that `yyparse' can call it. The function is sometimes referred to as a lexical scanner. In simple programs, `yylex' is often defined at the end of the Bison grammar file. If `yylex' is defined in a separate source file, you need to arrange for the token-type macro definitions to be available there. To do this, use the `-d' option when you run Bison, so that it will write these macro definitions into a separate header file `NAME.tab.h' which you can include in the other source files that need it. Note: Invoking Bison.
