4.1 The Parser Function yyparse
You call the function yyparse to cause parsing to occur. This
function reads tokens, executes actions, and ultimately returns when it
encounters end-of-input or an unrecoverable syntax error. You can also
write an action which directs yyparse to return immediately
without reading further.
- Function: int yyparse (void)
- The value returned by
yyparse is 0 if parsing was successful (return
is due to end-of-input).
The value is 1 if parsing failed (return is due to a syntax error).
In an action, you can cause immediate return from yyparse by using
these macros:
- Macro: YYACCEPT
-
Return immediately with value 0 (to report success).
- Macro: YYABORT
-
Return immediately with value 1 (to report failure).
