closescsi(2) is documented in the manpage but not in the header or source.

Perhaps it was missed when the code was written, or removed when
the thread locking was added?

    There is no record of closescsi ever existing.  I'm pretty sure
    the locking was there from day 1.  I may well have written the man
    page first (I often do that for new libraries to plan them out)
    and then simply forgotten to implement it.
    
    Thanks.
    
    I took the locking out, by the way, as it's insufficient.  If there
    is any contention for s at the time you're calling closescsi,
    you have problems.
