Examples/Documentation of bind9.4 libs

[Phil Nick]

Greetings all,
I am currently working on a multi-platform (Win32,AIX,Linux,SCO) c/c++
program which communicates over the internet on a regular interval.
Currently we use a hard coded IP for our software to be able to call home.
We are interested in adding the ability to use a dns name instead, but have
no control over how the system we are running on is configured and are not
able to make changes. I began searching for a library to allow our software
to resolve dns names. Bind seemed to be the best solution I have found.

My ultimate goal is the ability to specify our own resolv.conf with name
servers we know are good and resolve the names we need.

I have been able to make simple resolver.exe which does what I need. I used
nslookup as an example of how to use your libs. All I changed was where the
bind libs look for resolv.conf and made a version of nslookup which just
takes in one name and outputs a ip.

I am still trying to wrap my head around the bind code. Is the isc_app setup
meant to be thread safe? My problems begin to manifest when I try to use the
bind libs in a threaded environment. I am not sure if the problem is my
messing around with nslookup code or if the underlying libs are not meant to
be used in a threaded environment.


Thanks for your time,
Phil
