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:
Network definitions differences:
| Item | R5 stack | BONE stack | OpenBeOS stack |
|---|---|---|---|
| socket.h header file | be/net/socket.h | be/bone/sys/socket.h | posix/sys/socket.h |
| SOCK_DGRAM | 1 | 2 | idem as BONE |
| SOCK_STREAM | 2 | 1 | idem as BONE |
| SOCK_RAW | not defined | 3 | idem as BONE |
| SOCK_MISC | not defined | 255 | idem as BONE |
| SOL_SOCKET | 1 | 0xffffffff | idem as BONE |
| SO_DEBUG | 1 | 0x00000004 | idem as BONE |
| SO_REUSEADDR | 2 | 0x00000040 | idem as BONE |
| SO_NONBLOCK | 3 | 0x40000009 | idem as BONE |
| SO_REUSEPORT | 4 | 0x00000080 | idem as BONE |
| SO_FIONREAD | 5 | ? | ? |
| sockaddr | struct sockaddr { unsigned short sa_family; char sa_data[10]; }; | struct sockaddr { uint8 sa_len; uint8 sa_family; uint8 sa_data[30]; }; | idem as BONE |
| closesocket() | defined | not defined | defined, call close() |
| in.h header file | be/net/netinet/in.h, which in turn include be/net/socket.h | be/bone/netinet/in.h | posix/netinet/in.h |
