This directory contains a variety of clients that use the "/usr/include/dns_sd.h" APIs. Some of the clients are command-line oriented; some are graphical. Some of the clients, like the "dns-sd" command-line tool, can be built for a variety of platforms. Some of the clients only build for one platform, like "DNS Service Browser" and "DNS Service Registration", which use Objective C and Cocoa and only run on OS X 10.3 or later. Some of the clients can be built more than one way. For example, the "dns-sd" command-line tool can be built for OS X using both the XCode IDE, or using a simple command-line "make" command. What all clients have in common is that they all demonstrate how you can use the "/usr/include/dns_sd.h" APIs. The table below gives a summary of which clients build for which platforms.
