In do_producer(), there are the following lines in the main loop:
/* Send random lengths of data */ messages[i].length = (rand() % MAXLEN) + sizeof(size_t); iov[i].iov_len = messages[i].length;
The entire "struct sockmsg" is sent across the socket, so the first size_t in each message contains the length of the entire message (including the size_t). This size gets picked up at the recv(...,MSG_PEEK) line in do_consumer().
Thanks, Brent
