Member Function Documentation

virtual int XrdOucName2Name::lfn2pfn ( const char *  lfn,
char *  buff,
int  blen 
)
pure 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.
blenThe 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.
virtual int XrdOucName2Name::lfn2rfn ( const char *  lfn,
char *  buff,
int  blen 
)
pure 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.
blenThe 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.
virtual int XrdOucName2Name::pfn2lfn ( const char *  pfn,
char *  buff,
int  blen 
)
pure 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.
blenThe 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.
