+.Dt CK_HS_NEXT 3
+.Sh NAME
+.Nm ck_hs_next
+.Nd iterate to next entry in hash set
+.Sh LIBRARY
+Concurrency Kit (libck, \-lck)
+.Sh SYNOPSIS
+.In ck_hs.h
+.Ft bool 
+.Fn ck_hs_next "ck_hs_t *hs" "ck_hs_iterator_t *iterator" "void **entry"
+.Sh DESCRIPTION
+The
+.Fn ck_hs_next 3
+function will increment the iterator object pointed to by
+.Fa iterator
+to point to the next non-empty hash set entry. If
+.Fn ck_hs_next 3
+returns true then the pointer pointed to by
+.Fa entry
+is initialized to the current hash set key pointed to by the
+.Fa iterator
+object.
+.Pp
+It is expected that
+.Fa iterator
+has been initialized using the
+.Xr ck_hs_iterator_init 3
+function or statically initialized using CK_HS_ITERATOR_INITIALIZER.
+.Sh RETURN VALUES
+If
+.Fn ck_hs_next 3
+returns true then the object pointed to by
+.Fa entry
+points to a valid hash set key. If
+.Fa ck_hs_next 3
+returns false then the value of the object pointed to by
+.Fa entry
+is undefined.
+.Sh ERRORS
+Behavior is undefined if
+.Fa iterator
+or
+.Fa hs
+are uninitialized.
