SYNOPSIS

10     #include <ck_hs.h>
11
12     void *
13     ck_hs_apply_fn_t(void *key, void *closure);
14
15     bool
16     ck_hs_apply(ck_hs_t *hs, unsigned long hash, const void *key,
17         ck_hs_apply_fn_t *function, void *argument);
18

DESCRIPTION

20     The ck_hs_apply(3) function will lookup the hash set slot associated with
21     key and pass it to function pointed to by function for further action.
22     This callback may remove or replace the value by respectively returning
23     NULL or a pointer to another object with an identical key. The first
24     argument passed to function is a pointer to the object found in the hash
25     set and the second argument is the argument pointer passed to
26     ck_hs_apply(3).  If the pointer returned by function is equivalent to the
27     first argument then no modification is made to the hash set.
28

RETURN VALUES

30     Upon successful completion, ck_hs_apply(3) returns true and otherwise
31     returns false on failure.
