| Description: | MSG_NOSIGNAL doesn't exist on OS/X According to http://lists.apple.com/archives/macnetworkprog/2002/Dec/msg00091.html OS/X has "the socket option SO_NOSIGPIPE that prevents SIGPIPE from being raised when a write fails on a socket to which there is no reader; instead the write to the socket returns with the error EPIPE." ****** ADDITIONAL INFORMATION ****** [CC] res_pktccops.c -> res_pktccops.o res_pktccops.c: In function 'cops_sendmsg': res_pktccops.c:428: error: 'MSG_NOSIGNAL' undeclared (first use in this function) res_pktccops.c:428: error: (Each undeclared identifier is reported only once res_pktccops.c:428: error: for each function it appears in.) make[1]: *** [res_pktccops.o] Error 1 make: *** [res] Error 2 | ||
| Comments: | By: Olle Johansson (oej) 2009-11-04 06:07:00.000-0600 Found more information claiming that MSG_NOSIGNAL is not posix compliant and doesn't exist in BSD http://lists.policyd.org/pipermail/devel/2007-September/000468.html However the man page for send() on FreeBSD includes it. #define MSG_NOSIGNAL 0x20000 /* do not generate SIGPIPE on EOF */ The man page for OS/X Snow leopard only include two flags for send(): ---- The flags parameter may include one or more of the following: #define MSG_OOB 0x1 /* process out-of-band data */ #define MSG_DONTROUTE 0x4 /* bypass routing, use direct interface */ ---- By: Doug McCallum (dougm) 2009-12-03 17:25:16.000-0600 The same problem exists on OpenSolaris as well (also BSD origins). The Mac OS/X SO_NOSIGNAL doesn't exist on Solaris. It would be nice to have a common workaround, or better, a common solution.
