\skip include
\until dns.h
+ In this case we have used a configure script to generate a config.h file
+ that does all our inclusions for us, so that it can be compiled on
+ multiple platforms. If your platform supports the include files \c
+ stdlib.h and \c unistd.h, you can include these instead of using a
+ configure script.
+
The first included files are prerequisites that ldns needs to function.
The last one, of course, includes the functions of ldns itself.
