% cat '#P/ipifc'

The mechanism in libc, reading /net/tcp/0/local doesn't work very well
for multihomed hosts, since it returns just one number.  Moreover, all
the */local files return the address of the first interface, rather
than the one the connection is actually on.  That makes e.g. icmpfs do
the wrong thing if one of the interfaces doesn't have an advertised
route.

Is it possible to mix plan9 and unix programs together?
What I want to do is to use "ipinfo()" in plan9 to get all the network 
information and put into a common data structure. and another unix program 
can access the data structure to process the information.
Because both programs eventually will be compiled into .k file.
then you can use kl in plan9 to get executable file.

I am wondering if this will work.

you means 
	pcc filename.c -math will work.

Thank you very much

Just omit the linker flag.  Plan 9 header files contain a pragma to
tell the linker to load the library.

Try pcc -P filename.c and _read_ the file produced.  If there's anything
you don't understand in the output, please _do_ hesitate to ask a
question until you've read the relevant documentation.

I tried to do the following:
	pcc filename.c -lmath 
in Plan9.
	But the compiler told me that it can not find library file.
Could you please tell me how to do the same thing in Plan9?
Thank you very much

    I am porting a system built on the top of Unix to Plan9.
    Because the system use ioctle to get network address, network configuration,
    I find that plan9 doesn't support SIOCGIFADDR and SIOCFIFCONF.
    Could you please tell me how I can modify the plan9 to make it support them.

i think you'll find the idea is not to modify plan 9, but your system.
getting rid of ioctl was a feature.
