How to create a simple configurationfile parser?

[Jesper N?hr]

Hey there.

I'm writing a small application that has a belonging
configuration-file.

At the moment, I'm parsing the file with basic for-lops, but this is
pretty slow, and also I need to extend the parser to be able to read
more configuration-entries.

A friend of mine told me I should take a look at yacc/lex, and so I
googled for hours for some simple examples on this. I didn't really
find anything useful.

So my question is, could someone please post a simple example on how
to parse generic 'option = value' files with C and yacc/lex?

Thanks in advance.

If it really is "option = value", yacc/lex is almost certainly overkill. I'm
sure there are plenty of people who have implemented ".ini" file parsers
(which are option/value pairs classified into "sections"), you should be
able to Google up some source...
