Class XrdoucName2Name must be used for creating a name translation plug-in. This plug-in is specified by the 'oss.namelib' directive and when present makes the default oss plug-in load the plug-in shared library, locate the XrdOucgetName2Name function within and use it to obtain an instance of the XrdOucName2Name object to perform name translation prior to all subsequent storage system calls. The companion object, XrdOucName2NameVec, should also be defined in the same shared library (see the class definition below).

Map a logical file name to a physical file name.
- Parameters
-
lfn | -> Logical file name. |
buff | -> Buffer where the physical file name of an existing file is to be placed. It must end with a null byte. |
blen | The length of the buffer. |
- Returns
- Success: Zero. Failure: An errno number describing the failure; typically EINVAL - The supplied lfn is invalid. ENAMETOOLONG - The buffer is too small for the pfn.
Implemented in XrdOucN2N, and XrdOucN2No2p.

Map a logical file name to the name the file would have in a remote storage system (e.g. Mass Storage System at a remote location).
- Parameters
-
lfn | -> Logical file name. |
buff | -> Buffer where the remote file name is to be placed. It need not actually exist in that location but could be created there with that name. It must end with a null byte. |
blen | The length of the buffer. |
- Returns
- Success: Zero. Failure: An errno number describing the failure; typically EINVAL - The supplied lfn is invalid. ENAMETOOLONG - The buffer is too small for the pfn.
Implemented in XrdOucN2N, and XrdOucN2No2p.
