NAME

     ck_hs_put — store unique key into a hash set

LIBRARY

     Concurrency Kit (libck, -lck)

SYNOPSIS

     #include <ck_hs.h>

     bool
     ck_hs_put(ck_hs_t *hs, unsigned long hash, const void *key);

DESCRIPTION

     The ck_hs_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_HS_HASH(3)
     macro).

     If the call to ck_hs_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_hs_set(3) function.

RETURN VALUES

     Upon successful completion, ck_hs_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.
