+PR_GetAddrInfoByName
+====================
+
+Looks up a host by name. Equivalent to ``getaddrinfo(host, NULL, ...)``
+of RFC 3493.
+
+
+Syntax
+------
+
+.. code::
+
+ #include <prnetdb.h>
+
+ PRAddrInfo *PR_GetAddrInfoByName(
+ const char *hostname,
+ PRUint16 af,
+ PRIntn flags);
+
+
+Parameters
+~~~~~~~~~~
+
+The function has the following parameters:
+
+``hostname``
+ The character string defining the host name of interest.
+``af``
+ The address family. May be ``PR_AF_UNSPEC`` or ``PR_AF_INET``.
+``flags``
+ May be either ``PR_AI_ADDRCONFIG`` or
+ ``PR_AI_ADDRCONFIG | PR_AI_NOCANONNAME``. Include
+ ``PR_AI_NOCANONNAME`` to suppress the determination of the canonical
+ name corresponding to ``hostname``
+
+
+Returns
+~~~~~~~
+
+The function returns one of the following values:
+
+- If successful, a pointer to the opaque ``PRAddrInfo`` structure
+ containing the results of the host lookup. 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`.
