NAME¶

dpns_getreplicax - get the replica entries associated with a DPNS file in the name server

SYNOPSIS¶

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

int dpns_getreplicax (const char *path, const char *guid, const char *se, int *nbentries, struct dpns_filereplicax **rep_entries)

DESCRIPTION¶

dpns_getreplicax gets the replica entries associated with a DPNS file in the name server.

The file can be specified by path name or by guid. If both are given, they must point at the same file.

path

specifies the logical pathname relative to the current DPNS directory or the full DPNS pathname.

guid

specifies the Grid Unique IDentifier.

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 dpns_filereplicax structures allocated by the API. The client application is responsible for freeing the array when not needed anymore.

struct dpns_filereplicax {
	u_signed64	fileid;
	u_signed64	nbaccesses;
	time_t		ctime;		/* replica creation time */
	time_t		atime;		/* last access to replica */
	time_t		ptime;		/* replica pin time */
	time_t		ltime;		/* replica lifetime */
	char		r_type;		/* 'P' for Primary, 'S' for Secondary */
	char		status;
	char		f_type;		/* 'V' for Volatile, 'P' for Permanent */
	char		setname[37];
	char		poolname[CA_MAXPOOLNAMELEN+1];
	char		host[CA_MAXHOSTNAMELEN+1];
	char		fs[80];
	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 file does not exist.

EACCES

Search permission is denied on a component of the path prefix.

ENOMEM

Memory could not be allocated for unmarshalling the reply.

EFAULT

path and guid are NULL pointers or nbentries or rep_entries is a NULL pointer.

ENOTDIR

A component of path prefix is not a directory.

EINVAL

The length of guid exceeds CA_MAXGUIDLEN or the length of se exceeds CA_MAXHOSTNAMELEN or path and guid are both given and they point at a different file.

ENAMETOOLONG

The length of path exceeds CA_MAXPATHLEN or the length of a path component exceeds CA_MAXNAMELEN.

SENOSHOST

Host unknown.

SENOSSERV

Service unknown.

SECOMERR

Communication error.

ENSNACT

Name server is not running or is being shutdown.
