I'm trying to get DATlib
(ftp://ftp.informatik.uni-erlangen.de/pub/DATlib/) running on FreeBSD
4.1-STABLE. From what I can tell, all I need to do is to reimplement one
subroutine (see below).

How do I do this?

Matt

#include <sys/scsiio.h>

                unsigned char *cmd,int cmdlen,
                unsigned char *inbuf,int inbuflen,
                unsigned char *outbuf,int outbuflen,
                unsigned char *rqbuf,int rqbuflen

        scsireq_t       ucmd;
        int             r;

        memset (&ucmd, '\0', sizeof (ucmd));

        ucmd.flags      = 0;
        ucmd.timeout    = 1000;
        memcpy (ucmd.cmd, (caddr_t)cmd, cmdlen);
        ucmd.cmdlen     = cmdlen;
