+.In ck_hs.h
+.Ft bool
+.Fn ck_hs_reset_size "ck_hs_t *hs" "unsigned long size"
+.Sh DESCRIPTION
+The
+.Fn ck_hs_reset_size 3
+function will remove all keys stored in the hash
+set pointed to by the
+.Fa hs
+argument and create a new generation of the hash set that
+is preallocated for
+.Fa size
+entries.
+.Sh RETURN VALUES
+If successful,
+.Fn ck_hs_reset_size 3
+will return true and will otherwise return false on failure. This
+function will only fail if a replacement hash set could not be
+allocated internally.
+.Sh ERRORS
+Behavior is undefined if
+.Fa hs
+is uninitialized. Behavior is
+undefined if this function is called by a non-writer
+thread.
