NAME
ck_hs_move —
LIBRARY
Concurrency Kit (libck, -lck)SYNOPSIS
#include <ck_hs.h>
bool
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);
DESCRIPTION
Theck_hs_move(3) function will
initialize source from
destination. The hash function is set to
hash_cb, comparison function to
compare_cb and the allocator callbacks to
m. Further modifications to source
will result in undefined behavior. Concurrent
ck_hs_get(3)
and
ck_hs_fas(3)
operations to source are legal until the next write
operation to destination.
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.
RETURN VALUES
Upon successful completionck_hs_move(3) returns true and
otherwise returns false to indicate an error.
