    SubjectPROBLEM: select() says closed socket readable
    For linux 2.4.2, select() indicates socket ready for read on a
    socket that's never been connected. This is inconsistent with
    other versions of Unix including Linux 2.2.

    The following program demonstrates:

    #include <stdio.h>
    #include <unistd.h>
    #include <sys/time.h>
    #include <sys/types.h>
    #include <sys/socket.h>

    main(int argc, char *argv[])
    fd_set rfds;
    int retval;
    int sock;
    struct timeval tv;

    sock = socket(AF_INET, SOCK_STREAM, 0);
    if (sock == -1) abort();

    FD_SET(sock, &rfds);
    tv.tv_sec = 0;
    tv.tv_usec = 0;

    retval = select(sock + 1, &rfds, NULL, NULL, &tv);
    printf("retval from select(): %d\n", retval);

    } /* end main program */

    Output from "ver_linux" follows:
