LIBRARY¶Concurrency Kit (libck, -lck)
*hs, unsigned long
hash, const void
ck_rhs_fas(3) function will fetch and 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_fas(3) was successful
then the key specified by key was successfully stored
in the hash set pointed to by hs. The key must already
exist in the hash set, and is replaced by key and the
previous value is stored into the void pointer pointed to by the
previous argument. If the key does not exist in the
hash set then the function will return false and the hash set is unchanged.
This function is guaranteed to be stable with respect to memory usage.
RETURN VALUES¶Upon successful completion,
ck_rhs_fas(3) returns true and otherwise returns false on failure.
ERRORS¶Behavior is undefined if key or hs are uninitialized.
