Hi Sadish:

Take a look at the socket(9) man page, which is the KPI used by in-kernel 
consumers of sockets such as the NFS client and server, smbfs (via netsmb), 
ncpfs (via netncp), etc.  This is very close to the socket(2) system call API, 
but non-identical, so give a ping if you have any questions.
