ck_rhs_grow: enlarge hash set capacity

NAME

ck_rhs_grow - enlarge hash set capacity

LIBRARY

Concurrency Kit (libck, -lck)

SYNOPSIS

In ck_rhs.h Ft bool Fn ck_rhs_grow ck_rhs_t *hs unsigned long capacity

DESCRIPTION

The Fn ck_rhs_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_rhs is to round Fa capacity to the next power of two if it is not already a power of two.

RETURN VALUES

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

ERRORS

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