+.Dt CK_HS_MOVE 3
+.Sh NAME
+.Nm ck_hs_move
+.Nd move one from hash set to another
+.Sh LIBRARY
+Concurrency Kit (libck, \-lck)
+.Sh SYNOPSIS
+.In ck_hs.h
+.Ft bool
+.Fn ck_hs_move "ck_hs_t *destination" "ck_hs_t *source" "ck_hs_hash_cb_t *hash_cb" "ck_hs_compare_cb_t *compare_cb" "struct ck_malloc *m"
+.Sh DESCRIPTION
+The
+.Fn ck_hs_move 3
+function will initialize 
+.Fa source
+from
+.Fa destination .
+The hash function is set to
+.Fa hash_cb ,
+comparison function to
+.Fa compare_cb
+and the allocator callbacks to
+.Fa m .
+Further modifications to
+.Fa source
+will result in undefined behavior. Concurrent
+.Fn ck_hs_get 3
+and
+.Fn ck_hs_fas 3
+operations to
+.Fa source
+are legal until the next write operation to
+.Fa destination .
+.Pp
+This operation moves ownership from one hash set object
+to another and re-assigns callback functions to developer-specified
+values. This allows for dynamic configuration of allocation
+callbacks and is necessary for use-cases involving executable code
+which may be unmapped underneath the hash set.
+.Sh RETURN VALUES
+Upon successful completion
+.Fn ck_hs_move 3
+returns true and otherwise returns false to indicate an error.
