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 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.
