I'm looking for a programmatic interface to the Solaris ifconfig(1M) command.
Apparently Linux has the getifaddrs(3) command, but as far as I can tell this has not been ported to Solaris.
Short of attempting to use the code at the link above, is there any way to determine ifconfig(1M)-type data (network interface presence, state, etc.) without forking the system command and parsing the output?
I have an implementation here, IPv4-only based on SIOCGIFCONF ioctl()'s and IP family agnostic version using SIOCGLIFCONF:
http://code.google.com/p/openpgm/source/browse/trunk/openpgm/pgm/getifaddrs.c
Tested on SPARC/Solaris 10 and x86/OpenSolaris 2008.11 & 2009.06, LGPL 2.1 license.
getifaddrs() was recently integrated into the source code for future OpenSolaris & Solaris releases, but that doesn't help your code run on current releases:
Until then you'll need to use the SIOCGLIFCONF ioctls, which you should find lots of examples of in open source code, including the link you posted.
Real men use ioctl ;)
Take a look at if(7P).
