+PR_EnumerateHostEnt
+===================
+
+Evaluates each of the possible addresses of a :ref:`PRHostEnt` structure,
+acquired from :ref:`PR_GetHostByName` or :ref:`PR_GetHostByAddr`.
+
+
+Syntax
+------
+
+.. code::
+
+   #include <prnetdb.h>
+
+   PRIntn PR_EnumerateHostEnt(
+     PRIntn enumIndex,
+     const PRHostEnt *hostEnt,
+     PRUint16 port,
+     PRNetAddr *address);
+
+
+Parameters
+~~~~~~~~~~
+
+The function has the following parameters:
+
+``enumIndex``
+   The index of the enumeration. To begin an enumeration, this argument
+   is set to zero. To continue an enumeration (thereby getting
+   successive addresses from the host entry structure), the value should
+   be set to the function's last returned value. The enumeration is
+   complete when a value of zero is returned.
+``hostEnt``
+   A pointer to a :ref:`PRHostEnt` structure obtained from
+   :ref:`PR_GetHostByName` or :ref:`PR_GetHostByAddr`.
+``port``
+   The port number to be assigned as part of the :ref:`PRNetAddr`
+   structure. This parameter is not checked for validity.
+``address``
+   On input, a pointer to a :ref:`PRNetAddr` structure. On output, this
+   structure is filled in by the runtime if the result of the call is
+   greater than 0.
+
+
+Returns
+~~~~~~~
+
+The function returns one of the following values:
+
+-  If successful, the function returns the value you should specify in
+   the ``enumIndex`` parameter for the next call of the enumerator. If
+   the function returns 0, the enumeration is ended.
+-  If unsuccessful, the function returns -1. You can retrieve the reason
+   for the failure by calling :ref:`PR_GetError`.
+
+
+Description
+-----------
+
+:ref:`PR_EnumerateHostEnt` is a stateless enumerator. The principle input,
+the :ref:`PRHostEnt` structure, is not modified.
