CK_RHS_PUT(3)         DragonFly Library Functions Manual         CK_RHS_PUT(3)


NAME

     ck_rhs_put - store unique key into a hash set


LIBRARY

     Concurrency Kit (libck, -lck)


SYNOPSIS

     #include <ck_rhs.h>

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


DESCRIPTION

     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.


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.
