[Winpcap-users] pcap_sendqueue_transmit() has 128MB limit?

[Gianluca Varenni]

I haven't tested it myself, but I bet it's a limit of the OS itself. In 
practice the OS does not support a single write operation with a buffer of 
more than 128/256MB (and this limit probably depends on the OS flavor and 
version).

Why are you trying to transmit such a big single buffer?

Have a nice day
