SocketPlugin extions

Andreas.Raab
Hi Guys -

Attached the extensions for SocketPlugin which are based on David's code
(except I've folded them directly into SocketPlugin). It's basically
just two functions:
a) Being able to mark the socket as "reusable", e.g., setting
SO_REUSADDR/SO_REUSEPORT explicitly (the main reason for putting this
into a separate primitive is because on different platforms subtly
different actions need to be taken)
b) Being able to bind() a socket explicitly to an interface/port.

Cheers,
   - Andreas

So why do these need to be platform C code, versus invoking the  
proper methods in smalltalk code based on platform type ?

Because (IIRC) the only reliable way of using SO_REUSEPORT is something
like "#ifdef SO_REUSEPORT" because the versions under which it's
supported (and therefore must be used) are widely varied amongst the
Unix flavours. So just asking is this a "unix" platform isn't enough;
neither is "is this Linux" etc.

Cheers,

K, well you know the mac vm is using the unix socket support, so  
you'll need to talk to Ian about adding these prims.
