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.
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:
YYACCEPT
YYABORT
