ck_rhs_put ā€” store unique key into a hash set


Concurrency Kit (libck, -lck)


#include <ck_rhs.h>

ck_rhs_put(ck_rhs_t *hs, unsigned long hash, const void *key);


The ck_rhs_put(3) function will store the key specified by the key argument in the hash set pointed to by the hs argument. The key specified by key is expected to have the hash value specified by the hash argument (which was previously generated using the CK_RHS_HASH(3) macro).

If the call to ck_rhs_put(3) was successful then the key specified by key was successfully stored in the hash set pointed to by hs. The function will fail if a key with an equivalent value to key is already present in the hash set. For replacement semantics, please see the ck_rhs_set(3) function.

Return Values

Upon successful completion, ck_rhs_put(3) returns true and otherwise returns false on failure.


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