dpns_statg - get information about a DPNS file or directory in the name
int dpns_statg (const char *path, const char *guid, struct
int dpns_statr (const char *sfn, struct dpns_filestatg *statbuf)
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
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
time_t atime; /* last access to file */
time_t mtime; /* last file modification */
time_t ctime; /* last metadata modification
short fileclass; /* 1--> experiment, 2 -->
char status; /* ’-’ --> online, ’m’ -->
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
This routine returns 0 if the operation was successful or -1 if the
operation failed. In the latter case, serrno is set appropriately.
ENOENT The named file/directory does not exist or is a null
EACCES Search permission is denied on a component of the path
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
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.
