NAME¶

ck_rhs_move — move one from hash set to another

LIBRARY¶

Concurrency Kit (libck, -lck)

SYNOPSIS¶

#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);

DESCRIPTION¶

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.
