NAME

SYNOPSIS

10     #include <ck_rhs.h>
11
12     bool
13     ck_rhs_set(ck_rhs_t *hs, unsigned long hash, const void *key,
14         void **previous);
15

DESCRIPTION

17     The ck_rhs_set(3) function will store the key specified by the key argu‐
18     ment in the hash set pointed to by the hs argument. The key specified by
19     key is expected to have the hash value specified by the hash argument
20     (which was previously generated using the CK_RHS_HASH(3) macro).
21
22     If the call to ck_rhs_set(3) was successful then the key specified by key
23     was successfully stored in the hash set pointed to by hs.  If the key
24     already exists in the hash set, then it is replaced by key and the previ‐
25     ous value is stored into the void pointer pointed to by the previous
26     argument. If previous is set to NULL then key was not a replacement for
27     an existing entry in the hash set.
28

RETURN VALUES

30     Upon successful completion, ck_rhs_set(3) returns true and otherwise
31     returns false on failure.
32

ERRORS

34     Behavior is undefined if key or hs are uninitialized. The function will
35     also return false if the hash set could not be enlarged to accomodate key
36     insertion.
