hi all.
I don't know where to send this question to, so i post it here for
proximity.
I have a sun4u machine, and because i've seen , in all sun software,
there are various platforms, i.e. sun4c,sun4u,sun4m ..
What are they ? patch level ? machine dependant ?
Thanks.
Please, answer me via email because i'm not subscribed to this forum

sun4u - UltraSPARC UPA bus
sun4m - SuperSPARC
sun4c - SPARC
sun4d - SuperSPARC SS1000,SC2000 XD-bus
SUN4U1 - E10K - UPA on GigaPlane

Different architechtures for different SPARC processors and different
system buss

1. Sun's XDR routines won't work on Sun machines ...

... although they do on a NeXT.
Perhaps somebody can see an error in this code.

                .
                .
                .

        BufferSize += 50000;
        Buffer = malloc (BufferSize);
        Offset = strlen (ARCHIVED) + strlen (Description) + 1 + 4;
        sprintf (Buffer, ARCHIVED "%s", Description);
        xdrmem_create (&Stream, Buffer + Offset, BufferSize - Offset, XDR_ENCODE);
                .
                .
                .
        (in another function)
        if (Stream->x_op == XDR_ENCODE) {
                if (*Pointer != NULL) {
                        if (! xdr_bool (Stream, &NonNil))   <=== Bus error
                                return -1;
                        Next = 0;
                        if (DescriptionLoop (
                                Stream, Description, Descriptor, Pointer, &Next)
                            == -1)
                                return -1;
                }
                .
                .
                .

Some more info:
1.      The xdr_bool does the first write to the XDR stream, so it's very
        probable that something's wrong with the stream.
2.      The malloc for Buffer was ok, there should be enough memory for
        the stream.
3.      The Stream and NonNil variables seem to be ok, too.

I'm totally clueless. The routines have been heavily used on a NeXT without
any problem, but on a Sun4 (and IPX) they never make it beyond that point.

Any ideas are greatly apreciated.
