Re: [libvirt] [C# bindings][Pathces] Marshaling corrections, coverage and new sample
Okay, you're right I8 is just fine there because
DomainInterfaceStatsStruct and DomainBlockStatsStruct just contain
long long members and long long is always 64bit width. An int is
always 32bit width, so the only thing that needs special handling is
the long type in C, as it is compiler and platform dependent if it's
32bit or 64bit width.
I applied and pushed the 3 remaining patches now. I also tested them
on 32bit Windows and 64bit Linux.

Hi Matthias,
sorry for the response delay I've been very busy.
I was also surprised that this marshaling works without IntPtr, anyway I
have double check results against virsh unde Windows/.Net, Windows/Mono,
Ubuntu 10.10/Mono (64 bits) and it works fine.
Anyway, I can try to put IntPtr to be coherent. What do you think ?
Regards,
Arnaud
