CK_HS_MOVE(3)         DragonFly Library Functions Manual         CK_HS_MOVE(3)


ck_hs_move - move one from hash set to another


Concurrency Kit (libck, -lck)


#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);


The ck_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.


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