CK_HS_GROW(3)            BSD Library Functions Manual            CK_HS_GROW(3)

NAME
     ck_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.
