18 // TBonjourBrowser //
19 // //
20 // This class consists of one main member function, //
21 // BrowseForServiceType(), that looks for the service. //
22 // The rest of the class wraps the various bits of Bonjour service //
23 // browser. The static callback function is marked with the DNSSD_API //
24 // macro to make sure that the callback has the correct calling //
25 // convention on Windows. //
26 // //
27 // Bonjour works out-of-the-box on MacOS X. On Linux you have to //
28 // install the Avahi package and run the avahi-daemon. To compile //
29 // these classes and run Avahi on Linux you need to install the: //
30 // avahi //
31 // avahi-compat-libdns_sd-devel //
32 // nss-mdns //
33 // packages. After installation make sure the avahi-daemon is started. //
