But the old comment still remains: +static +int usb_mmap(pcap_t* handle) +{ + int len = ioctl(handle->fd, MON_IOCQ_RING_SIZE); + if (len < 0) + return 0; + + /* write access is required, because we create pcap_hdr in-place */ + errno = 0; + handle->buffer = mmap(0, len, PROT_READ, + MAP_SHARED, handle->fd, 0); + return handle->buffer != MAP_FAILED; Maybe you want to remove it? I'm working on getting the kernel patch up to date, but there were some changes to mmap interface in 2.6.20-rc1 (like VM_RESERVED is gone, apparently), so not today. Maybe on Sunday. -- Pete ------------------------------------------------------------------------- Take Surveys. Earn Cash.
