STAT ( 2 ) STAT ( 2 ) NAME stat, fstat - get file status SYNOPSIS #include #include int stat (path, bur) char *path; struct stat •bur; int rstat (tildes, bur) int tildes; struct stat •bur; DESCRIPTION Path points to a path name naming a file. Read, write or execute permission of the named file is not required, but all directories listed in the path name leading to the file must be searchable. Stat obtains information about the named file. Similarly, fstat obtains information about an open file known by the file descriptor fildes, obtained from a successful open, ere at, dup , fcntl, or pipe system call. Buf is a pointer to a stat structure into which information is placed concerning the file. The contents of the structure pointed to by buf include the following members: dev_t ino_t ushort short ushort ushort dev_t off_t time_t time_t time_t st_dev; st_ino; st_mode; st_nlink; st_uid; st_gid; st_rdev; st_size; st_atime; st_mtime; st_ctime; /• ID of device containing •I I* a directory entry for this file •/ I* Inode number *I I• File mode; see mknod(2) •I I* Number of links •I I* User ID of the file's owner •I I* Group ID of the file's group •I I* ID of device •I I* This entry is defined only for *I I• character special or block •I I* special files •I I* File size in bytes *I I• Time of last access *I I* Time of last data modification *I I• Time of last file status change •I I* Times measured in seconds •I I* since 00:00:00 GMT, *I I* Jan. 1, 1970 •I st_atime Time when file data was last accessed. Changed by the following system calls: creat(2), mknod(2), pipe(2), utime (2), and read(2). st_mtime Time when data was last modified. Changed by the following system calls: creat(2), mknod(2), pipe(2), utime(2), and write(2). - 1 -
