PR_EnumerateAddrInfo
====================
Enumerates each of the possible network addresses of a ``PRAddrInfo``
structure, acquired from :ref:`PR_GetAddrInfoByName`.
Syntax
~~~~~~
.. code::
#include <prnetdb.h>
void *PR_EnumerateAddrInfo(
void *enumPtr,
const PRAddrInfo *addrInfo,
PRUint16 port,
PRNetAddr *result);
Parameters
~~~~~~~~~~
The function has the following parameters:
``enumPtr``
The index pointer of the enumeration. To begin an enumeration, this
argument is set to ``NULL``. To continue an enumeration (thereby
getting successive addresses from the ``PRAddrInfo`` structure), the
value should be set to the function's last returned value. The
enumeration is complete when a value of ``NULL`` is returned.
``addrInfo``
A pointer to a ``PRAddrInfo`` structure returned by
:ref:`PR_GetAddrInfoByName`.
``port``
The port number to be assigned as part of the :ref:`PRNetAddr`
structure. This parameter is not checked for validity.
``result``
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
not ``NULL``.
Returns
~~~~~~~
The function returns the value you should specify in the ``enumPtr``
parameter for the next call of the enumerator. If the function returns
``NULL``, the enumeration is ended.
Description
-----------
:ref:`PR_EnumerateAddrInfo` is a stateless enumerator. The principle input,
the ``PRAddrInfo`` structure, is not modified.
