#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_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 * /
