Name
lcg_la - get the list of aliases for a given LFN, GUID or SURLSynopsis
int lcg_la (char *file, char *vo, char *conf_file, int insecure, char ***lfns);
int lcg_lax (char *file, char *vo, char *conf_file, int insecure, char ***lfns, char *errbuf, int errbufsz);
int lcg_la2 (char *file, int nobdii, char *vo, char ***lfns, char *errbuf, int errbufsz);
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 actually ignored.
- insecure
- This argument is actually ignored.
- 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.
- 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
- 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.
