DESCRIPTION

The ck_ht_entry_key_direct() function will return the key value as specified in the object pointed to by the entry argument.

It is expected that the entry is associated with a hash table initialized with CK_HT_MODE_DIRECT (see ck_ht_init(3) for more information).

ERRORS

Behavior is undefined if entry has not been initialized.
