Help-----what the API "getnetconfig" can not be found in Linux

Google [url]http://www.cs.biu.ac.il/cgi-bin/man?netconfig+4[/url] says this is a
Solaris/SunOS-specific thing. It doesn't exist in the same way on
Linux; there aren't typically any device nodes for your eth0..eth9
devices.[0] You can figure out how many network devices there are and
what their IP (and IPV6, if present) addresses are by popen()ing
/sbin/ifconfig and parsing what you get back. There are ioctls you can
call and files in /proc you can read to get that information, of course,
but running ifconfig is probably faster than rewriting it.

Also, when you're asking for things like this, you typically get better
results when you explain more of the larger picture. Don't say, "What
is the equivalent to Win32MultiMediaCrud() in Linux?", say "I need to
keep audio/video synced to +/- 0.05 seconds in the video player I'm
writing; how could I do that?" What are you using getnetconfig() et al
*for* here, in other words? HTH anyway,

[0] There can be, but that particular kernel option is only rarely
turned on.
