ck_ht_grow_spmc3
Resize a hash table if necessary
Usage
#include <ck_ht.h>
bool
ck_ht_grow_spmc(ck_ht_t *ht, uint64_t capacity);
Library
Concurrency Kit (libck, -lck)
Overview
The ck_ht_grow_spmc() function will resize the hash table in order to be able to at least store the number of entries specified by capacity at a load factor of one. The default load hash table load factor is 0.5. If you wish to minimize the likelihood of memory allocations for a hash table meant to store n entries then specify a capacity of 2n. The default behavior of ck_ht is to round capacity to the next available power of two if it is not already a power of two.
This function is safe to call in the presence of concurrent ck_ht_get_spmc(3) operations.
Return values
Upon successful completion ck_ht_grow_spmc() returns true and otherwise returns a false value.
Errors
Behavior is undefined if ht is uninitialized. The function will only return false if there are internal memory allocation failures.
Releases
Unchanged in 5 releases since Debian 8 (Jessie).
