NAME¶
lfc_registerfiles - register list of files with their corresponding replica
entry
SYNOPSIS¶
#include <sys/types.h>
#include "lfc_api.h"
int lfc_registerfiles (int nbfiles, struct lfc_filereg
*files, int *nbstatuses, int
**statuses)
DESCRIPTION¶
lfc_registerfiles registers a list of files with their corresponding
replica entry. If the lfn is already registered, the guid is optional and only
the replica is added (after checking that filesize and possibly checksum
match). If the lfn is not registered yet, the guid is mandatory for the LFC.
The lfn and the replica get registered.
- nbfiles
- specifies the number of files in the array files.
- files
- is a pointer to an array of lfc_filereg structures provided by the
application.
struct lfc_filereg {
char *lfn;
char *guid;
mode_t mode;
u_signed64 size;
char *csumtype;
char *csumvalue;
char *server;
char *sfn;
};
- nbstatuses
- will be set to the number of replies in the array of statuses.
- statuses
- will be set to the address of an array of integer statuses allocated by
the API. The client application is responsible for freeing the array when
not needed anymore. Individual statuses are 0 if the operation was
successful or set to the serrno value in case of error.
RETURN VALUE¶
This routine returns 0 if the operation was successful or -1 if the operation
failed. In the latter case,
serrno is set appropriately.
ERRORS¶
- ENOENT
- A component of lfn prefix does not exist or lfn is a null
pathname.
- E2BIG
- Request too large (max 1 MB).
- ENOMEM
- Memory could not be allocated for marshalling the request or unmarshalling
the reply.
- EACCES
- Search permission is denied on a component of the lfn prefix or the
file does not exist and write permission on the parent directory is denied
or write permission on the file itself is denied.
- EFAULT
- files, nbstatuses or statuses is a NULL pointer.
- EEXIST
- The sfn exists already.
- ENOTDIR
- A component of lfn prefix is not a directory.
- EISDIR
- The lfn exists already and is not a regular file.
- EINVAL
- nbfiles is not strictly positive, the length of one of the
guids exceeds CA_MAXGUIDLEN or the length of server
exceeds CA_MAXHOSTNAMELEN or lfn and guid are both given and they
point at a different file.
- ENOSPC
- The name server database is full.
- ENAMETOOLONG
- The length of lfn exceeds CA_MAXPATHLEN or the length of an
lfn component exceeds CA_MAXNAMELEN or the length of
sfn exceeds CA_MAXSFNLEN.
- SENOSSERV
- Service unknown.
- SEINTERNAL
- Database error.
- SECOMERR
- Communication error.
- ENSNACT
- Name server is not running or is being shutdown.
