Open, Read, Write, pipes, Fork and Exec are included in POSIX
standards.  Sockets, for instance, are not currently in any approved
POSIX standards.  Therefore, code written using sockets is *NOT*
guaranteed portable in a POSIX environment (e.g.  Open VMS, CTOS or
POSIX-compliant MVS, for instance).  Sockets are a BSD extension
(which is now included in System V).  Sockets packages exist for other
operating systems, but they're not "open" in the sense of formally
standardized.  Your semantics may vary...

Could you please explain this?  What is "Posix syntax"?  I'm not
familiar with that term...
