NAME

lfc_listreplica - list replica entries for a given file

SYNOPSIS

#include <sys/types.h>
#include "lfc_api.h"

struct lfc_filereplica *lfc_listreplica (const char *path, const char *guid, int flags, lfc_list *listp)

DESCRIPTION

lfc_listreplica lists replica entries for a given file. This routine returns a pointer to a structure containing the current replica entry.

struct lfc_filereplica {
	u_signed64	fileid;
	u_signed64	nbaccesses;
	time_t		atime;		/* last access to replica */
	time_t		ptime;		/* replica pin time */
	char		status;
	char		f_type;		/* 'V' for Volatile, 'P' for Permanent */
	char		poolname[CA_MAXPOOLNAMELEN+1];
	char		host[CA_MAXHOSTNAMELEN+1];
	char		fs[80];
	char		sfn[CA_MAXSFNLEN+1];
};

path: specifies the logical pathname.
guid: specifies the Grid Unique IDentifier.
flags: may be one of the following constant:

CNS_LIST_BEGIN: the first call must have this flag set to allocate buffers and initialize pointers.
CNS_LIST_CONTINUE: all the following calls must have this flag set.
CNS_LIST_END: final call to terminate the list and free resources.

RETURN VALUE

This routine returns a pointer to a structure containing the current replica entry if the operation was successful or NULL if all entries have been returned or if the operation failed. In the latter case, serrno is set appropriately.

EXAMPLES

A C program listing the replicas fo a given sfn could look like:

	int flags;
	lfc_list list;
	struct lfc_filereplica *lp;
	flags = CNS_LIST_BEGIN;
	while ((lp = lfc_listreplica (sfn, NULL, flags, &list)) != NULL) {
		flags = CNS_LIST_CONTINUE;
		/* process the entry */
		.....
	}
	(void) lfc_listreplica (sfn, NULL, CNS_LIST_END, &list);

ERRORS

ENOENT: The named file does not exist.
EACCES: Search permission is denied on a component of the parent directory.
ENOMEM: Memory could not be allocated for the output buffer.
EFAULT: path and guid are NULL pointers or listp is a NULL pointer.
ENOTDIR: A component of path prefix is not a directory.
EINVAL: The length of guid exceeds CA_MAXGUIDLEN or path and guid are both given and they point at a different file.
ENAMETOOLONG: The length of path exceeds CA_MAXPATHNAMELEN.
SENOSHOST: Host unknown.
SENOSSERV: Service unknown.
SECOMERR: Communication error.
ENSNACT: Name server is not running or is being shutdown.
