STAT(II)                      8/5/73                     STAT(II)



NAME
     stat - get file status

SYNOPSIS
     (stat = 18.)
     sys stat; name; buf

     stat(name, buf)
     char *name;
     struct inode *buf;

DESCRIPTION
     Name  points  to a null-terminated string naming a file; buf
     is the address of a 36(10) byte buffer into  which  informa-
     tion  is  placed  concerning the file.  It is unnecessary to
     have any permissions at all with respect to  the  file,  but
     all directories leading to the file must be readable.  After
     stat, buf has the following structure (starting offset given
     in bytes):

     struct inode {
        char  minor;         /* +0: minor device of i-node */
        char  major;         /* +1: major device */
        int   inumber;       /* +2 */
        int   flags;         /* +4: see below */
        char  nlinks;        /* +6: number of links to file */
        char  uid;           /* +7: user ID of owner */
        char  gid;           /* +8: group ID of owner */
        char  size0;         /* +9: high byte of 24-bit size */
        int   size1;         /* +10: low word of 24-bit size */
        int   addr[8];       /* +12: block numbers or device number */
        int   actime[2];     /* +28: time of last access */
        int   modtime[2];    /* +32: time of last modification */
     };

     The flags are as follows:

      100000   i-node is allocated
      060000   2-bit file type:
           000000   plain file
           040000   directory
           020000   character-type special file
           060000   block-type special file.
      010000   large file
      004000   set user-ID on execution
      002000   set group-ID on execution
      001000   save text image after execution
      000400   read (owner)
      000200   write (owner)
      000100   execute (owner)
      000070   read, write, execute (group)
      000007   read, write, execute (others)

DIAGNOSTICS
     Error  bit (c-bit) is set if the file cannot be found.  From
     C, a -1 return indicates an error.
