There's also no mention here that at most 8 lines can be added. Hopefully we never need to go beyond that number (however arbitrary 8 is). Is the semicolon mandatory? Seems to me whatever format is required needs to be well documented. With respect to the strings and the parsing done, should I 'assume' that the config_lookup_string() will know how to read the config file where elements span multiple lines.... In particular, is "line1," "line2" read/returned as "line1,line2"? I would think a continuation "\" marker would be necessary: "line1," \ "line2" I would also think the comma would be outside the quotes, but don't have experience with the API in question. Since I don't have a way to test this - I'm curious while coding this up if you checked that both lines were read when parsing? Secondarily, there's some extraneous spaces which perhaps need to be cleaned up. Since the code later on will separate based on ",".
