/sys$common/syshlp/helplib.hlb CC, Socket Routines, shutdown  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Shuts down all or part of a bidirectional connection on a socket.
    It can disallow further receives, further sends, or both.

    Syntax:

      #include <socket.h>

      int shutdown(int s, int how);
