     entry

LIBRARY

SYNOPSIS
     #include <ck_ht.h>

     uintptr_t
     ck_ht_entry_key_direct(ck_ht_entry_t *entry);

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).

RETURN VALUES
     ck_ht_entry_key_direct() returns 0 if the entry is empty. Otherwise, it
     returns the key value stored in the object pointed to by the entry
     argument.

ERRORS
     Behavior is undefined if entry has not been initialized.
