Dear SCO Customer,

libsocket, corrects the following problems in the socket library:

        1. recv(3sock) incorrectly returns EINVAL or ENOTSOCK.

        2. socketpair(3sock) can return unexpected errors.

PTF7054B contains:

        /usr/lib/Nlibsocket.so

The release notes displayed prior to installation can be found in:

        /var/sadm/pkg/ptf7054/install/ptf7054.txt

7.0.1 Patch for Multiple Drivers, Autopush, and Header Files, in addition to 
this SLS, as PTF7038C includes fixes to the streams driver which will affect 
the use of sockets on the system.
