LFC_STAT(3)
NAME
lfc_stat - get information about a LFC file or directory in the name
server
SYNOPSIS
#include <sys/types.h> #include "lfc_api.h" int lfc_lstat (const char *path, struct lfc_filestat *statbuf) int lfc_stat (const char *path, struct lfc_filestat *statbuf) int lfc_statx (const char *path, struct lfc_fileid *file_uniqueid, struct lfc_filestat *statbuf)
DESCRIPTION
lfc_stat gets information about a LFC file or directory in the name
server.
lfc_lstat is identical to lfc_stat except for symbolic links.
lfc_lstat retrieves information about the link itself, while lfc_stat
gets information about the file/directory referenced by the symbolic
link.
lfc_statx returns the same information plus the file unique id (name server hostname and file id). The file can be specified by path name or by file_uniqueid. If both are given, file_uniqueid is used.
- path specifies the logical pathname relative to the current LFC
- directory or the full LFC pathname.
- The structure pointed to by statbuf contains the following members:
- u_signed64 fileid; /* entry unique identifier */
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 */ - 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 path
- name.
- EACCES Search permission is denied on a component of the path
- prefix.
- EFAULT path or statbuf is a NULL pointer.
- 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.
- SENOSHOST Host unknown.
- SENOSSERV Service unknown.
- SECOMERR Communication error.
- ENSNACT Name server is not running or is being shutdown.
