[Vm-dev] How to read from and write to a Unix domain socket

[David T. Lewis]

The socket plugin updates seem to be missing in the Cog branch (checking
both VMMaker-oscog-EstebanLorenzano.158 and VMMaker.oscog-eem.160). It
should be OK to pull in the updates directly from VMMaker trunk, i.e. from
VMMaker-dtl.274, although it may be that platform support code will also
be needed for the Cog branch (I did not check this).
