CK_HS_GROW(3) BSD Library Functions Manual CK_HS_GROW(3)NAMEck_hs_grow — enlarge hash set capacity
LIBRARY
Concurrency Kit (libck, -lck)
SYNOPSIS
#include <ck_hs.h>
bool
ck_hs_grow(ck_hs_t *hs, unsigned long capacity);
DESCRIPTION
The 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 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 capacity of 2n. The default behavior of
ck_hs is to round capacity to the next power of two if it is not already
a power of two.
RETURN VALUES
Upon successful completion, ck_hs_grow(3) returns true and otherwise
returns false on failure.
ERRORS
Behavior is undefined if hs is uninitialized. This function will only
return false if there are internal memory allocation failures.
