            Description

            The current implementation of GetSockOpt service for option SO_ERROR returns any previous error seen for a socket. Even errors occured during SetSockOpt or GetSockOpt services.

            According to Posix standard, SO_ERROR should only return the pending socket errors. These refer to problems occuring asynchronously during socket operation. (e.g. when a connection was lost)

            In addition, GetSockOpt SO_ERROR is expected to clear the last error, thus a subsequent call will not return an error anymore.
