Hello,

recv() in Linux 2.6 kernel has a fix for returning the original length of the packet even when the packet is truncated using the MSG_TRUNC flag. 

However, is there a fix for this in FREEBSD???
recv() does not return the original length of the packet in freebsd. 
I need to get the original length of the packet on freebsd.

Please HELP !!!!

Thanks,
Ramya
