CK_HT_GROW_SPMC(3) BSD Library Functions Manual CK_HT_GROW_SPMC(3)
NAME
ck_ht_grow_spmc — resize a hash table if necessary
LIBRARY
Concurrency Kit (libck, -lck)
SYNOPSIS
#include <ck_ht.h>
bool
ck_ht_grow_spmc(ck_ht_t *ht, uint64_t capacity);
DESCRIPTION
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 ta‐
ble 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.
