Hi!
I want to use the getopts unit but I fear, I don't understand the docu: If I have long
options, what is returned by getLongOpts? In the docu-example (see below), c can be
'1', '2', '3', ... or #0 or 'a', 'b', ... I don't understand, what getlongopts='9'
means.
Can soneone explain me, how to use getopts with two or three short and long options?
cut uot from units.pdf:
c := getlongopts ( � abc:d:012 � ,@theopts [ 1 ] , optionindex ) ;
case c of
� 1 � , � 2 � , � 3 � , � 4 � , � 5 � , � 6 � , � 7 � , � 8 � , � 9 � :
begin
wr i teln ( �Got opt ind : � , c )
end ;
# 0 : begin
wr i te ( � Longopt ion : � , theopts [ optionindex ] . name ) ;
if theopts [ optionindex ] . has_arg >0 then
writeln ( � With value : � , optarg )
else
writeln
end ;
� a � : writeln ( � Option a . � ) ;
� b � : writeln ( � Option b . � ) ;
� c � : writeln ( � Option c : � , optarg ) ;
� d � : writeln ( � Option d : � , optarg ) ;
� ? � , � : � : writeln ( � Error with opt : � , optopt ) ;
end ; { case }
Thanks, RUDOLF
