I would also suggest that implementing this as a perl utility might be much simpler than adding more c code still ... and such tasks are not time critical so perl is the ideal fehicle in my eyes ... tobi | | Jake | | Jake Brutlag | Network Analyst | Microsoft WebTV | | -- | Unsubscribe mailto:[EMAIL PROTECTED] | Help mailto:[EMAIL PROTECTED] | Archive http://www.ee.ethz.ch/~slist/rrd-developers | WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi | | -- ______ __ _ /_ __/_ / / (_) Oetiker, ETZ J97, ETH, 8092 Zurich, Switzerland / // _ \/ _ \/ / phoneto:+41(0)1-632-5286 faxto:+41(0)1-632-1517 /_/ \.__/_.__/_/ mailto:[EMAIL PROTECTED] http://people.ee.ethz.ch/~oetiker -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-developers WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
