May be ``PR_AF_UNSPEC`` or ``PR_AF_INET``. +``flags`` + May be either ``PR_AI_ADDRCONFIG`` or + ``PR_AI_ADDRCONFIG | PR_AI_NOCANONNAME``.

Use + :ref:`PR_EnumerateAddrInfo` to inspect the :ref:`PRNetAddr` values stored + in this structure. When no longer needed, this pointer must be + destroyed with a call to :ref:`PR_FreeAddrInfo`. +- If unsuccessful, ``NULL``. You can retrieve the reason for the + failure by calling :ref:`PR_GetError`. |
