Here is diff. I cam across the error: In function (for each function in iostat.c)multiple declaration (of the the functions)I  think everything is good enough.Still if someone can figure it out and tell me.

Hello,I am porting the iostat from FreeBSD.I have problem with the function devstat_compute_statistics()
Here is how its used in FreeBSD ans I tried the compute_stats() in dragonfly but still need this equivalent to be correct
So, please give me the correct usage of compute_stats similar to devstat_compute_statistics in the FreeBSD, here it is:        if (devstat_compute_statistics(&cur.dinfo->devices[di],
             &last.dinfo->devices[di], busy_seconds,
             DSM_KB_PER_TRANSFER, &kb_per_transfer,
             DSM_TRANSFERS_PER_SECOND, &transfers_per_second,
             DSM_MB_PER_SECOND, &mb_per_second, DSM_NONE) != 0)
                 errx(1, "%s", devstat_errbuf);
Also, is it OK if we call getnumdevs() without any arguments (its similar to freebsd devstat_getdevs()).
The FreeBSD uses:switch (devstat_getdevs(NULL, &cur)) {
         case -1:
                errx(1, "%s", devstat_errbuf);
         case 1:
                 cmdiostat("refresh", NULL);
 }I am still trying to remove some warnings and error. Will mail you if need more help.pratyush.kshirsagar (@
