ISO transmission w/ libraw

[Ichiro S. <ic...@fn...>]

Hi,

    I've been trying ISO packet transmission without any success.
I attach my code below, 's.cc' for the sender side and 'r.cc'
for the receiver.  These are running on two machines, sender and
receiver each.  What am I missing?  (Bus reset handling and
FCP transmission worked fine with similar code.)

    System info.:
kernel: Linux 2.2.16
ieee1394: 2.2.17-20001012
libraw: 0.8.2
NIC: D-Link DFW-500 (OHCI compat.)

Thanks a lot
