NAME¶

lfc_getreplicas - get the replica entries associated with a list of GUIDs

SYNOPSIS¶

#include <sys/types.h> #include "lfc_api.h" int lfc_getreplicas (int nbguids, const char **guids, const char *se, int *nbentries, struct lfc_filereplicas **rep_entries)

DESCRIPTION¶

lfc_getreplicas gets the replica entries associated with a list of GUIDs.

nbguids

specifies the number of guids in the array guids.

guids

specifies the list of Grid Unique IDentifiers.

se

allows to restrict the replica entries to a given SE.

nbentries

will be set to the number of entries in the array of replicas.

rep_entries

will be set to the address of an array of lfc_filereplicas structures allocated by the API. The client application is responsible for freeing the array when not needed anymore.

struct lfc_filereplicas {
	char		guid[CA_MAXGUIDLEN+1];
	int		errcode;
	u_signed64	filesize;
	time_t		ctime;		/* GUID creation time */
	char		csumtype[3];
	char		csumvalue[33];
	time_t		r_ctime;	/* replica creation time */
	time_t		r_atime;	/* last access to replica */
	char		status;
	char		host[CA_MAXHOSTNAMELEN+1];
	char		sfn[CA_MAXSFNLEN+1];
};

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

The named guid does not exist.

ENOMEM

Memory could not be allocated for marshalling the request or unmarshalling the reply.

EFAULT

guids, nbentries or rep_entries is a NULL pointer.

EINVAL

nbguids is not strictly positive, the length of one of the guids exceeds CA_MAXGUIDLEN or the length of se exceeds CA_MAXHOSTNAMELEN.

SENOSHOST

Host unknown.

SENOSSERV

Service unknown.

SEINTERNAL

Database error.

SECOMERR

Communication error.

ENSNACT

Name server is not running or is being shutdown.
