Nah. This is an internal interface whose behavior we do not provide stability for. Indeed, I know of at least one corner-case bug in its current behavior. We do not generally document the behavior of internal interfaces (though we strive to document even internal syscalls). For example, dlctl(3)'s description is basically just "this exists", which is basically useless... Philip Guenther
