NAME
lcg_la - get the list of aliases for a given LFN, GUID or SURL
SYNOPSIS
import lcg_util
(int returncode,
listOfString lfns,
string errmsg
) lcg_lax (string file,
string vo,
string conf_file,
int insecure,
listOfString lfns)
(int returncode,
listOfString lfns,
string errmsg
) lcg_la2 (string file,
int nobdii,
string vo,
listOfString lfns)
DESCRIPTION
lcg_la
gets the list of aliases for a given LFN, GUID or SURL.
- file
-
specifies the Logical File Name, the Grid Unique IDentifier or the Site URL.
An SURL scheme can be
sfn:
for a classical SE or
srm:.
- nobdii
-
If set to a non-zero value, it means that you don't want to make BDII calls to get LFC endpoint.
So, you have to define the environment variable 'LFC_HOST'.
- vo
-
specifies the Virtual Organization the user belongs to. If it is not specified,
the environment variable LCG_GFAL_VO will be used.
- conf_file
-
This argument is currently ignored.
- insecure
-
This argument is currently ignored.
The access to the Replica Catalog or the LFC is done according to the endpoints published
in MDS.
- lfns
-
will be set by the routine to the address of the array of pointers to the
aliases. The application should free both the logical file names and the array
of pointers.
NOTE
The environment variable LCG_GFAL_INFOSYS must point to the BDII, unless
nobdii
is set to a non-zero value.
To use the RLS as catalog instead of the LFC, the environment variable
LCG_CATALOG_TYPE must explicitely be set to "edg". By default, it is set to "lfc".
RETURN VALUE
This routine returns 0 if the operation was successful or -1 if the operation
failed. In the latter case,
errno
is set appropriately.
ERRORS
- ENOENT
-
The named file does not exist.
- EFAULT
-
file,
vo
or
lfns
is an invalid pointer.
- EINVAL
-
file
has an invalid syntax.
- ECOMM
-
Communication error.
- ENAMETOOLONG
-
vo
is too long.
- EPROTONOSUPPORT
-
Access method not supported.
