<H1>Haiku Network Kit: R5 compatibility issues</H1>
|
2004-01-03 21:18:06 +03:00
|
|
|
|
|
|
|
|
<P>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.<BR>
|
|
|
|
|
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.<BR>
|
|
|
|
|
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...
|
|
|
|
|
</P>
|
|
|
|
|
<P>So, here we are. By design, we must:
|
|
|
|
|
<UL>
|
|
|
|
|
<LI>Provide backward binary compatibility with old, non-standard, network definitions used
|
|
|
|
|
by apps linked against R5 network stack;
|
|
|
|
|
<LI>But use the standard/de-facto BSD network definitions, to increase Unix network apps ports ease under
