Out of curiosity: What do your link settings look like now? Philipp On 13.05.2014 12:31, Aaron_Wright@selinc.com wrote:
I'm not 100% sure why, but this was caused by linking with winsock32. As soon as I stopped linking with that old library, the multicasting worked like a charm.

I previously used ASIO from Boost 1.49 to send out multicast UDP messages up to 64K bytes in size without a problem. Now with ASIO from Boost 1.55 I
can't seem to send out a multicast UDP message greater than 1500 bytes. I get this error:
Code=1784 Category=system Message=The supplied user buffer is not valid for the requested operation
I've looked at the code between Boost 1.49 and 1.55, (basic_datagram_socket.hpp, datagram_socket_services.hpp, win_iocp_socket_service_base.hpp and ipp) and very little has changed. Am I missing something that changed between the two?
I'm using Windows and Microsoft Visual Studio 2010 for both 1.49 and 1.55.
Hopefully someone has an idea of where to look. Thanks. ---
