Thanks for testing the RC. The Linux manpage describe the flag as "don't SIGPIPE on stream-oriented socket when the other end breaks the connection". Since the socket in use is SOCK_DGRAM it looks like a no-op to me; probably just habit on the part of the writer, and you could happily define it to zero.
I think OS X OS X requires SO_NOSIGPIPE instead. This one builds too, but I don't know if I'm messing things up. #ifndef MSG_NOSIGNAL #define MSG_NOSIGNAL SO_NOSIGPIPE #endif
I'd not use SO_NOSIGPIPE even given the (presumed) similar function; that will be a socket-option bit and there's no telling what it might do when used for a send flag. Unless someone knowing more speaks up I'll remove that flag from the send call. -- Cheers, Jeremy -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
