NAME¶
ck_hs_apply
—
apply a function to hash set value
LIBRARY¶
Concurrency Kit (libck, -lck)
SYNOPSIS¶
#include
<ck_hs.h>
void *
ck_hs_apply_fn_t
(void
*key, void
*closure);
bool
ck_hs_apply
(ck_hs_t
*hs, unsigned long
hash, const void
*key, ck_hs_apply_fn_t
*function, void
*argument);
DESCRIPTION¶
The
ck_hs_apply
(3)
function will lookup the hash set slot associated with
key and pass it to function pointed to by
function for further action. This callback may remove
or replace the value by respectively returning NULL or a pointer to another
object with an identical key. The first argument passed to
function is a pointer to the object found in the hash
set and the second argument is the argument pointer
passed to ck_hs_apply
(3). If
the pointer returned by function is equivalent to the
first argument then no modification is made to the hash set.
RETURN VALUES¶
Upon successful completion,
ck_hs_apply
(3) returns true
and otherwise returns false on failure.
