ck_ht_grow_spmc: resize a hash table if necessary

NAME

ck_ht_grow_spmc - resize a hash table if necessary

LIBRARY

Concurrency Kit (libck, -lck)

SYNOPSIS

In ck_ht.h Ft bool Fn ck_ht_grow_spmc ck_ht_t *ht uint64_t capacity

DESCRIPTION

The Fn 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 Fa 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 Fa 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_spmc3 operations.

RETURN VALUES

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

ERRORS

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