Yes, fd is set to 10, and errno is set to 0x4a.

The actual lines where errstr is set is in pcap-bpf.c:

        (void) ioctl(fd, BIOCSBLEN, (caddr_t)&v);

        (void)strncpy(ifr.ifr_name, device, sizeof(ifr.ifr_name));
        if (ioctl(fd, BIOCSETIF, (caddr_t)&ifr) < 0) {
                sprintf(ebuf, "%s: %s", device, pcap_strerror(errno));
                goto bad;
        }

Ideas?
