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. .Sh RETURN VALUES Upon successful completion, .Fn ck_hs_grow 3 returns true and otherwise returns false on failure. .Sh ERRORS Behavior is undefined if .Fa hs is uninitialized. This function will only return false if there are internal memory allocation failures. .Sh SEE ALSO .Xr ck_hs_init 3 , .Xr ck_hs_destroy 3 , .Xr CK_HS_HASH 3 , .Xr ck_hs_iterator_init 3 , .Xr ck_hs_next 3 , .Xr ck_hs_get 3 , .Xr ck_hs_put 3 , .Xr ck_hs_set 3 , .Xr ck_hs_fas 3 , .Xr ck_hs_remove 3 , .Xr ck_hs_count 3 , .Xr ck_hs_reset 3 , .Xr ck_hs_reset_size 3 , .Xr ck_hs_stat 3 .Pp Additional information available at http://concurrencykit.org/
