All of the pointers in the ``hostentry`` + structure point to data saved in this buffer. This buffer is + referenced by the runtime during a call to :ref:`PR_EnumerateHostEnt`. +``bufsize`` + Number of bytes in the ``buf`` parameter. The buffer must be at least + :ref:`PR_NETDB_BUF_SIZE` bytes. +``hostentry`` + This structure is allocated by the caller.

You can retrieve the reason for the + failure by calling :ref:`PR_GetError`. + + +Description +~~~~~~~~~~~ + +:ref:`PR_GetHostByAddr` is used to perform reverse lookups of network +addresses. That is, given a valid network address (of type +:ref:`PRNetAddr`), :ref:`PR_GetHostByAddr` discovers the address' primary +name, any aliases, and any other network addresses for the same host. -- cgit v1.2.3
