CK_HT_GROW_SPMC(3) Library Functions Manual CK_HT_GROW_SPMC(3)

ck_ht_grow_spmcresize a hash table if necessary

Concurrency Kit (libck, -lck)

#include <ck_ht.h>

ck_ht_grow_spmc(ck_ht_t *ht, uint64_t capacity);

The () 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.

Upon successful completion ck_ht_grow_spmc() returns true and otherwise returns a false value.

Behavior is undefined if ht is uninitialized. The function will only return false if there are internal memory allocation failures.
