socket programming without RTnet.

Thanks your comments.

What I want is to make some network applications just as I did with vxWorks. A 'network application' means using socket/bind/sendto/recvfrom etc APIs to send and receive data to/from outside of me or between internal tasks.

I can't figure out what kernel space' and 'userland' mean. Well I am strange with embedded linux on ppc860 because I stayed with other RTOSs such as vxWorks and Nuclues. Would you explain more in detail?

Currently I patched my kernel 2.4.20 with RTAI and loaded RTAI modules after booting. Also I loaded my 'network application' using insmod.

I still wonder why there is not any standard socket APIs in the linux ppc-embedded kernel and why I can't use sys_socket/sys_bind/sys_recvfrom/sys_sendto in net/socket.c in loadable application.
