  28 DESCRIPTION
  29 -----------
  30
  31
  32 The :c:func:`hashkit_create` function initializes a hashkit object for use. If
  33 you pass a NULL argument for hash, then the memory for the object is
  34 allocated. If you specify a pre-allocated piece of memory, that is
  35 initialized for use.
  36
  37 The :c:func:`hashkit_clone` function initializes a hashkit object much like
  38 :c:func:`hashkit_create`, but instead of using default settings it will use
  39 the settings of the ptr hashkit object.
  40
  41 The :c:func:`hashkit_free` frees any resources being consumed by the hashkit
  42 objects that were initialized with :c:func:`hashkit_create` or :c:func:`hashkit_clone`.
  43
  44 The :c:func:`hashkit_is_allocated` reports where the memory was allocated
  45 for a hashkit object.
  46

  48 ------------
  49 RETURN VALUE
  50 ------------
  51
  52
  53 :c:func:`hashkit_create` and :c:func:`hashkit_clone` will return NULL on
  54 failure or non-NULL on success.
  55
  56 :c:func:`hashkit_is_allocated` returns true if the memory for the hashkit
  57 object was allocated inside of :c:func:`hashkit_create` or
  58 :c:func:`hashkit_clone`, otherwise it is false and was user-supplied memory.
