Perhaps another receive flag?
I now understand that setting the MSG_TRUNC flag is only applicable for PF_PACKET. I do not argue about that any more. :-) What I question is the return value when receiving from a local socket using recv(). Sorry, I don't know what the POSIX standard has to say about receiving from local sockets in contrast to UDP sockets as my only reference are the man pages. According to "man 2 recv", on success the return value is the "the number of bytes received". Since patch-2.6.8, UDP is always returning the full packet length. I'd like to see local sockets (PF_UNIX) to do the same. Does POSIX stipulate a different behaviour for local sockets?
