NAME

     ck_rhs_set — store key into a hash set

LIBRARY

     Concurrency Kit (libck, -lck)

SYNOPSIS

     #include <ck_rhs.h>

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

DESCRIPTION

     The ck_rhs_set(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_set(3) was successful then the key specified by key was successfully
     stored in the hash set pointed to by hs.  If the key already exists in the hash set, then it
     is replaced by key and the previous value is stored into the void pointer pointed to by the
     previous argument. If previous is set to NULL then key was not a replacement for an existing
     entry in the hash set.

RETURN VALUES

     Upon successful completion, ck_rhs_set(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.
