Different targets, as in different ip destinations for each datagram? That puts you out of luck in my mind I'm afraid.
Due to the fact that the sending content is not static i can't use sendfile.
Is there a way to merge differenent sendto with different targets to one system call?
if there's no ready-made solution, I would be glad for design suggestions of such a wrapper kernel module.if you can pick off data bound for the same destination, you can coalesce them in userspace from within your app, and only call sendto after a certain data threshold is reached. That would reduce your sendto overhead somewhat. Other than that, I think you're out of luck.

thanks

The purpose is to avoid the system call overhead due to the massive use of SendTo in my code.
any help will be appreciated...
