int XrdOucN2N::concat_fn ( const char *  prefix, int  pfxlen, const char *  path, char *  buffer, int  blen  )

private

Referenced by lfn2pfn(), and lfn2rfn().

int XrdOucN2N::lfn2pfn ( const char *  lfn, char *  buff, int  blen  )

virtual

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.

Implements XrdOucName2Name.

int XrdOucN2N::lfn2rfn ( const char *  lfn, char *  buff, int  blen  )

virtual

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.

Implements XrdOucName2Name.

int XrdOucN2N::pfn2lfn ( const char *  pfn, char *  buff, int  blen  )

virtual

Map a physical file name to it's logical file name.

Parameters

pfn	-> Physical file name. This is always a valid name of either an existing file or a file that could been created.
buff	-> Buffer where the logical file name is to be placed. It need not actually exist but could be created 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.

Implements XrdOucName2Name.
