Short: Morgengrauen diffs
From: Lars
Date 000630
Type: Patch
State: Mostly adapted in 3.2.9-dev.259

These are the simul_efuns needed to run LDMud with the Morgengrauen lib:

                   : efun::read_file(name, start);

    return res;
}

int send_udp(string host, int port, mixed message)
{
    int a, b, c, d;

    /* Non-numeric hostnames require a blocking hostname lookup
     * in the main mud thread. As for our purposes fixed addresses
     * are sufficient, disallow everything else.
     */
    if (sscanf(host, "%d.%d.%d.%d", a, b, c, d) != 4)
        return 0;

    return efun::send_udp(host, port, message);
}

{
    return send_udp(host, port, message);
}

----------------------------------------------------

These are those diffs of the Morgengrauen driver 2000.01.18 against it's
parent version, amylaar 3.2.1@141, which have no counterpart in LDMud..

The random.c used by Morgengrauen. LDMud uses the Mersenne Twister which
should be as good as this one, if not better.
