stat(5)stat(5)NAMEstat - data returned by stat system call
SYNOPSIS
#include <sys/types.h>
#include <sys/stat.h>
DESCRIPTION
The system calls stat, lstat and fstat return data in a stat structure,
which is defined in stat.h and includes the following members:
dev_t st_dev;
ino_t st_ino;
mode_t st_mode;
nlink_t st_nlink;
uid_t st_uid;
gid_t st_gid;
dev_t st_rdev;
off_t st_size;
timespec_t st_atim;
timespec_t st_mtim;
timespec_t st_ctim;
long st_blksize;
blkcnt_t st_blocks;
char st_fstype[_ST_FSTYPSZ];
The constants used in the st_mode field are also defined in this file:
#define S_IFMT /* type of file */
#define S_IAMB /* access mode bits */
#define S_IFIFO /* fifo */
#define S_IFCHR /* character special */
#define S_IFDIR /* directory */
#define S_IFNAM /* XENIX special named file */
#define S_INSEM /* XENIX semaphore subtype of IFNAM */
#define S_INSHD /* XENIX shared data subtype of IFNAM */
#define S_IFBLK /* block special */
#define S_IFREG /* regular */
#define S_IFLNK /* symbolic link */
#define S_IFSOCK /* socket */
#define S_ISUID /* set user id on execution */
#define S_ISGID /* set group id on execution */
#define S_ISVTX /* save swapped text even after use */
#define S_IREAD /* read permission, owner */
#define S_IWRITE /* write permission, owner */
#define S_IEXEC /* execute/search permission, owner */
#define S_ENFMT /* record locking enforcement flag */
#define S_IRWXU /* read, write, execute: owner */
#define S_IRUSR /* read permission: owner */
#define S_IWUSR /* write permission: owner */
#define S_IXUSR /* execute permission: owner */
#define S_IRWXG /* read, write, execute: group */
