NAME ck_ht_gc -- perform maintenance on a hash table LIBRARY Concurrency Kit (libck, -lck) SYNOPSIS #include <ck_ht.h> bool ck_ht_gc(ck_ht_t *ht, unsigned long cycles, unsigned long seed); DESCRIPTION The ck_ht_gc() function will perform various maintenance routines on the hash table pointed to by ht, including defragmentation of probe se- quences with respect to tombstones and in the case that the delete workload hint has been passed, recalculation of probe sequence bounds. The cycles argument is used to indicate how many hash table entries should be subject to attempted maintenance. If cycles is 0, then main- tenance is performed on the complete hash table. The seed argument de- termines the start location of the maintenance process. If cycles is non-zero, it is recommended that seed is some random value. If the delete hint has been passed, the function will require an additional 12% of memory (with respect to existing memory usage of the set), until operation completion. RETURN VALUES Upon successful completion, ck_ht_gc(3) returns true and otherwise re- turns false on failure due to memory allocation failure. ERRORS This function will only return false if there are internal memory allo- cation failures.
