NAME
lcg_lg - get the GUID for a given LFN or SURL
SYNOPSIS
import lcg_util
(int returncode,
string guid,
string errmsg
) lcg_lgx (string lfn_or_surl,
string vo,
string conf_file,
int insecure)
(int returncode,
string guid,
string errmsg
) lcg_lg2 (string lfn_or_surl,
int nobdii,
string vo)
DESCRIPTION
lcg_lg
gets the GUID for a given LFN or SURL.
- lfn_or_surl
-
specifies the Logical File Name 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.
- guid
-
specifies a buffer (minimum 37 bytes) to receive the actual guid.
- errbuf
-
specifies a buffer of size
errbufsz
to receive detailed error messages. If this pointer is NULL, the message goes
to stderr. The pointer should not be NULL if the application is a daemon or is
multi-threaded.
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
-
lfn_or_surl,
vo
or
guid
is an invalid pointer.
- EINVAL
-
lfn_or_surl
has an invalid syntax.
- ECOMM
-
Communication error.
- ENAMETOOLONG
-
vo
is too long.
- EPROTONOSUPPORT
-
Access method not supported.
