You've made three mistakes. The first one was posting your question to
comp.misc, instead of comp.lang.c (to where I've cross-posted my
response, and hopefully you'll get more intelligent answers).
Your second mistake is assuming that 'fscanf' works the way you think it
will. This is why you need sage advice from the folks who are C
experts. I guarantee you it works absolutely nothing like F*rtr*n.
Your third mistake, which is probably the one you really thought you
were asking advice about, is the format of the .newsrc file. It is
_not_ a group followed by whitespace followed by a number. It is more
along the following lines:
<group>[:|!][<number range>][,<number range>] ...
where: <group> is, of course, the newsgroup in it's format, that we all
know and love(hate?). [:|!] means either a colon (:) or a bang (!)
(the bang means unsubscribed). [<number range>] is optional, and can be
either a single number, or two numbers separated by a dash. Number
ranges are separated by commas.
Someone who is a better 'rn' expert may be able to amplify/correct this,
as this is only from observation of the actual file in use.

Good luck. You're going to need it.
