ck_rhs_move3
Move one from hash set to another
Usage
#include <ck_rhs.h>
bool
ck_rhs_move(ck_rhs_t *destination, ck_rhs_t *source, ck_rhs_hash_cb_t *hash_cb, ck_rhs_compare_cb_t *compare_cb, struct ck_malloc *m);
Library
Concurrency Kit (libck, -lck)
Overview
The ck_rhs_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_rhs_get(3) and ck_rhs_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 completion ck_rhs_move(3) returns true and otherwise returns false to indicate an error.
