static VALUE
bsock_close_write(VALUE sock)
{
    rb_io_t *fptr;

    GetOpenFile(sock, fptr);
    if (!(fptr->mode & FMODE_READABLE)) {
        return rb_io_close(sock);
    }
    shutdown(fptr->fd, SHUT_WR);
    fptr->mode &= ~FMODE_WRITABLE;

    return Qnil;
}

Disallows further write using shutdown system call.

Example

UNIXSocket.pair {|s1, s2|
  s1.print "ping"
  s1.close_write
  p s2.read        #=> "ping"
  s2.print "pong"
  s2.close
  p s1.read        #=> "pong"
}
