NAME
     ck_rhs_put_unique -- unconditionally store unique key into a hash set

LIBRARY
     Concurrency Kit (libck, -lck)

SYNOPSIS
     #include <ck_rhs.h>

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

DESCRIPTION
     The  ck_rhs_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_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 cause undefined behavior if a key with an equivalent value 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_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.
