The latest (2.7) glibc (which is much newer than what uClibc is based on) has a similar way of introducing additional checks in various parts of the code. However, it relies on getifaddrs() to determine the existance of an interface instead of checking the /proc filesystem. Which as you are implying might be a better way to do it. /Ricard -- Ricard Wolf Wanderlöf ricardw(at)axis.com Axis Communications AB, Lund, Sweden www.axis.com Phone +46 46 272 2016 Fax +46 46 13 61 30 _______________________________________________ uClibc mailing list [email protected] http://busybox.net/cgi-bin/mailman/listinfo/uclibc
