The current implementation of pthread_sigmask violates POSIX:
extern "C" int
pthread_sigmask (int operation, const sigset_t *set, sigset_t *old_set)
{
return handle_sigprocmask (operation, set, old_set, _my_tls.sigmask);
}POSIX requires that sigprocmask returns -1 and sets errno on failure, but that pthread_sigmask returns a positive error value on failure (and for QoI leaves errno untouched). http://pubs.opengroup.org/onlinepubs/9699919799/functions/sigprocmask.html -- Eric Blake ebl...@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
