NAME

stat.h, stat - 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>.

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_IFDOOR /* door */

#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 */

#define S_IRGRP /* read permission: group */

#define S_IWGRP /* write permission: group */

#define S_IXGRP /* execute permission: group */

#define S_IRWXO /* read, write, execute: other */

#define S_IROTH /* read permission: other */

#define S_IWOTH /* write permission: other */

#define S_IXOTH /* execute permission: other */

The following macros are for POSIX conformance (see standards(5)):

#define S_ISBLK(mode) block special file

#define S_ISCHR(mode) character special file

#define S_ISDIR(mode) directory file

#define S_ISFIFO(mode) pipe or fifo file

#define S_ISREG(mode) regular file

#define S_ISSOCK(mode) socket file

The following symbolic constants are defined as distinct integer values outside of the range [0, 999 999 999], for use with the futimens() and utimensat() functions:

#define UTIME_NOW use the current time
#define UTIME_OMIT no time change
