GNU adns

Advanced, easy to use, asynchronous-capable DNS client library and
utilities.
-

adns is a resolver library for C (and C++) programs, and a collection
- of useful DNS resolver utilities. In contrast with the existing
- interfaces, gethostbyname et al and libresolv, it has the following
- features:

+C library
+
+ In contrast with the standard interfaces, gethostbyname et al and
+ libresolv, it has the following features:
* It is reasonably easy to use for simple programs which just want
to translate names to addresses, look up MX records, etc.
* It can be used in an asynchronous, non-blocking, manner. Many
TCP in case of long replies or queries, or to other nameservers if
several are available. It has sensible handling of bad responses
etc.

DNS utility programs
adns also comes with a number of utility programs for use from the
easily in from the command line and from shell scripts to do
simple lookups. In a more advanced mode it can be used as a
general-purpose DNS helper program for scripting languages which
- can invoke and communicate with subprocesses. See the [1]usage
- message for a summary of its capabilities.

+ can invoke and communicate with subprocesses. See the [1]adnshost
+ usage message for a summary of its capabilities.
- adns requires a real nameserver like [2]BIND or [3]Dents running on
- the same system or a nearby one, which must be willing to provide
- `recursive service'. I.e., adns is a `stub resolver'. All properly
- configured UN*X and GNU systems will already have such nameserver(s);
- they are usually listed in /etc/resolv.conf.

Documentation
I'm afraid there is no manual yet. However, competent C programmers
- should be able to use the library based on the [4]commented adns.h
+ should be able to use the library based on the [2]commented adns.h
header file, and the usage messages for the programs should be
sufficient.

I'd be pleased if you would let me know if you're using my library in
your project, and what you think of it.
