ck_hs_grow: enlarge hash set capacity


ck_hs_grow - enlarge hash set capacity


Concurrency Kit (libck, -lck)


In ck_hs.h Ft bool Fn ck_hs_grow ck_hs_t *hs unsigned long capacity


The Fn ck_hs_grow 3 function will resize the hash set in order to be able to store at least the number of entries specified by Fa capacity at a load factor of one. The default hash set load factor is 0.5. If you wish to minimize the likelihood of memory allocations for a hash set meant to store n entries, then specify a Fa capacity of 2n. The default behavior of ck_hs is to round Fa capacity to the next power of two if it is not already a power of two.


Upon successful completion, Fn ck_hs_grow 3 returns true and otherwise returns false on failure.


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