NAME

dpns_statg - get information about a DPNS file or directory in the name server  

SYNOPSIS

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

int dpns_statg (const char *path, const char *guid, struct dpns_filestatg *statbuf)

int dpns_statr (const char *sfn, struct dpns_filestatg *statbuf)  

DESCRIPTION

dpns_statg gets information about a DPNS file or directory, having the given GUID, in the name server.

dpns_statr retrieves information about the given replica.

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

guid
specifies the Grid Unique IDentifier.
path
specifies the logical pathname relative to the current DPNS directory or the full DPNS pathname.
sfn
is either the Site URL or the Physical File Name for the replica.

The structure pointed to by statbuf contains the following members:

u_signed64     fileid;                 /* entry unique identifier */

char           guid[CA_MAXGUIDLEN+1]   /* GUID */

mode_t         filemode;               /* see below */

int            nlink;                  /* number of files in a directory */

uid_t          uid;

gid_t          gid;

u_signed64     filesize;

time_t         atime;                  /* last access to file */

time_t         mtime;                  /* last file modification */

time_t         ctime;                  /* last metadata modification */

short          fileclass;              /* 1--> experiment, 2 --> user */

char           status;                 /* '-' --> online, 'm' --> migrated */

char           csumtype[3];

char           csumvalue[33];

filemode is constructed by OR'ing the bits defined in <sys/stat.h> under Unix or "statbits.h" under Windows/NT:

S_IFLNK        0xA000           symbolic link

S_IFREG        0x8000           regular file

S_IFDIR        0x4000           directory

S_ISUID        0004000          set user ID on execution

S_ISGID        0002000          set group ID on execution

S_ISVTX        0001000          sticky bit

S_IRUSR        0000400          read by owner

S_IWUSR        0000200          write by owner

S_IXUSR        0000100          execute/search by owner

S_IRGRP        0000040          read by group

S_IWGRP        0000020          write by group

S_IXGRP        0000010          execute/search by group

S_IROTH        0000004          read by others

S_IWOTH        0000002          write by others

S_IXOTH        0000001          execute/search by others
 

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/directory does not exist or is a null pathname.
EACCES
Search permission is denied on a component of the path prefix.
EFAULT
path or statbuf is a NULL pointer.
EINVAL
The length of the guid component exceeds CA_MAXGUIDLEN or path and guid are both given and they point at a different file.
ENOTDIR
A component of path prefix is not a directory.
ENAMETOOLONG
The length of path exceeds CA_MAXPATHLEN or the length of a path component exceeds CA_MAXNAMELEN or the length of the sfn exceeds CA_MAXSFNLEN.
SENOSHOST
Host unknown.
SENOSSERV
Service unknown.
SECOMERR
Communication error.
ENSNACT
Name server is not running or is being shutdown.
