iterate to next entry in hash set
ck_rhs_next(3) function will
increment the iterator object pointed to by iterator to
point to the next non-empty hash set entry. If
ck_rhs_next(3) returns true then
the pointer pointed to by entry is initialized to the
current hash set key pointed to by the iterator object.
It is expected that iterator has been initialized using the ck_rhs_iterator_init(3) function or statically initialized using CK_RHS_ITERATOR_INITIALIZER.
ck_rhs_next(3) returns true
then the object pointed to by entry points to a valid
hash set key. If
returns false then the value of the object pointed to by
entry is undefined.
