When I originally wrote this, I think all these things were defined in
the PKG_ADD function. Then I think someone suggested I move them into
the .cc file as DEFUNX_DLD calls. In fact, there is a macro in there
as follows
// This macro must start with DEFUN_DLD so that the automatic collection
// of function helps can take place.
#define DEFUN_DLD_SOCKET_CONSTANT(name, help ) \
DEFUNX_DLD ( #name, F ## name, FS ## name, args, nargout, help) \
{ return octave_value( name ); };
It does seem strange that the readline autocompletion thinks that
AF_INET exists, but I get the same error when trying to access it. If
you are in a bind, you can look at the <sys/socket.h> header file and
use the integer equivalent. If someone has a suggestion on how to fix
this, I will make the changes. I also promise to fix the
documentation so it says something better than "See the socket() man
pages".
