NAME ck_rhs_fas -- fetch and store key in hash set LIBRARY Concurrency Kit (libck, -lck) SYNOPSIS #include <ck_rhs.h> bool ck_rhs_fas(ck_rhs_t *hs, unsigned long hash, const void *key, void **previous); DESCRIPTION The 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 pre- vious 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 guar- anteed 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.
