NAME ck_hs_put_unique -- unconditionally store unique key into a hash set LIBRARY Concurrency Kit (libck, -lck) SYNOPSIS #include <ck_hs.h> bool ck_hs_put_unique(ck_hs_t *hs, unsigned long hash, const void *key); DESCRIPTION The ck_hs_put_unique(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_HS_HASH(3) macro). If the call to ck_hs_put(3) was successful then the key specified by key was successfully stored in the hash set pointed to by hs. The function will cause undefined behavior if a key with an equivalent value is already present in the hash set. For replacement semantics, please see the ck_hs_set(3) function. RETURN VALUES Upon successful completion, ck_hs_put_unique(3) returns true and other- wise returns false on failure. ERRORS 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. The function will result in undefined behavior if called for an already inserted key value.
