This class provides access to sockets for interprocess communication.
The message protocol is preliminary, until someone tells me how
other smalltalk's socket interfaces look like.
Currently, only IP and UNIX domain sockets are supported.
Code for appletalk is included, but was never tested ...
More may be added in the future.
(the code is prepared for things like SNA or decNet;
however, right now, this code is empty and needs a little work.
Implementing those is pretty straight forward, once the address
data structures are known.)
Due to historic reasons (I started this class, before I got hold of some
code using ST-80 Sockets i.e. RemoteInvocation), there is some old interface
still provided.
This will vanish; use the #family:type: or #newTCPxxx and #newUDPxxx interfaces,
together with the bind/listen and accept calls,
which are meant to be compatible to ST-80's UnixSocketAccessor interface.
ST/X does not use IPSocketAddress, UDSocketAddress etc; all addressing
is done by passing appropriate string- or byteArray objects containing
the addresses. This may change, too.
TODO: cleanup historic leftovers, implement other than inet domain stuff.
(mhmh - how can I test those ?)
change to raise more signals on errors.
Help - could someone who has a linux machine connected to an appletalk
net please test this (and send bug fixes ...)
