OpenBeOS Network Kit: R5 compatibility

+ +

Unfortunatly, R5 and sooner (net_server based) network stack development header file (/develop/headers/be/net/socket.h) definition of +network structures and constantes are not BSD standard ones.
+BONE, otherwise, try to follow at best these standards definitions which, +in turn, break binary compatibility with R5 network apps compiled for R5 network stack.
+Hence why you needs to link against libsocket.so, libbind.so and libbnetapi.so BONE apps instead of +R5 libnet.so and libnetapi.so libraries... +

+

So, here we are. By design, we must: +
