SYNOPSIS


.In 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 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.
