The problem with the socket code you included and ESIX V is that ESIX
does not have a true socket library.  The listen() call in ESIX is
based on t_listen(), not like BSD.  Therefore, all BSD software using
sockets will _not_ work with ESIX without major changes to the socket
calls. 

The Network programmers manual for ESIX gives the definitions of the
socket library calls, but does not explain there function.

Your best off to convert the code to use the TLI functions instead of
working with their incompatible socket library.

BTW, ESIX is working on System V/R4 for production next year. That
release will have complete socket implementation.
