We can use either of these to implement a missing explicit_bzero(). explicit_memset() is supported on NetBSD. NetBSD hitherto didn't have a way to implement explicit_bzero() other than the fallback variant. memset_explicit() is the C23 standard, so we use it as first preference. It is currently supported on: - NetBSD 11 - FreeBSD 15 - glibc 2.43 It doesn't provide additional coverage, but as it's the new standard, its availability will presumably grow.
