[Dotgnu-pnet-commits] CVS: pnetlib/System/Platform Errno.cs,NONE,1.1 SocketMethods.cs,NONE,1.1

[Rhys Weatherley <address@hidden>]

Update of /cvsroot/dotgnu-pnet/pnetlib/System/Platform
In directory subversions:/tmp/cvs-serv8784/System/Platform

Added Files:
        Errno.cs SocketMethods.cs 
Log Message:


Move the "Platform.SocketMethods" class into "System.dll" and
make it "internal", to prevent it being exported publicly from
"mscorlib.dll" and hence a security problem.
