It is probable that the OpenBSD stack totally ignored signals and therefore wouldn't necessarily do the right thing. The FreeBSD stack is better integrated with POSIX support. > 2) EINTR isn't listed as one of the possible return values for > send(), but we seem to be getting it: > > http://ecos.sourceware.org/docs-3.0/ref/net-common-tcpip-manpages-send.html > Very weird. The current FreeBSD documentation also does not mention EINTR. However Linux man pages do, as does the POSIX standard. In general net stack calls return EINTR only if the thread is broken out of a wait by cyg_thread_release(), and only POSIX signal handling generally does that. If the application is using signals, then maybe the signal masks need to be set up differently. -- Nick Garnett eCos Kernel Architect eCosCentric Limited http://www.eCosCentric.com The eCos experts Barnwell House, Barnwell Drive, Cambridge, UK.
