SYNOPSIS

10     #include <ck_hs.h>
11
12     bool
13     ck_hs_move(ck_hs_t *destination, ck_hs_t *source,
14         ck_hs_hash_cb_t *hash_cb, ck_hs_compare_cb_t *compare_cb,
15         struct ck_malloc *m);
16

DESCRIPTION

18     The ck_hs_move(3) function will initialize source from destination.  The
19     hash function is set to hash_cb, comparison function to compare_cb and
20     the allocator callbacks to m.  Further modifications to source will
21     result in undefined behavior. Concurrent ck_hs_get(3) and ck_hs_fas(3)
22     operations to source are legal until the next write operation to
23     destination.
24
25     This operation moves ownership from one hash set object to another and
26     re-assigns callback functions to developer-specified values. This allows
27     for dynamic configuration of allocation callbacks and is necessary for
28     use-cases involving executable code which may be unmapped underneath the
29     hash set.
30

RETURN VALUES

32     Upon successful completion ck_hs_move(3) returns true and otherwise
33     returns false to indicate an error.
