+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.
