arc4random_solaris.h
Log message:
Cleanup portable arc4random fork detection code:
1. Use "len" parameter instead of sizeof(*rs).
2. Simplify the atfork handler to be strictly async signal safe by
simply writing to a global volatile sig_atomic_t object, and then
checking for this in _rs_forkdetect(). (Idea from discussions with
Szabolcs Nagy and Rich Felker.)
3. Use memset(rs, 0, sizeof(*rs)) to match OpenBSD's MAP_INHERIT_ZERO
fork semantics to avoid any skew in behavior across platforms.
