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 otherwise 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.
