I.e. is it >safe per POSIX to have SA_RESTART for SIG_DFL action initially at >application startup (before any application actions)? The initial value for sa_flags seems to be unspecified. In practice, it is 0 in FreeBSD. This probably only matters if you use sigaction() to find the old value and write a modified value, since SA_RESTART doesn't affect SIG_DFL actions (it only affects caught signals). It doesn't matter for the other flags, since the "BSD default" for them is off. Bruce
