3/15/72 STAT (II)
NAME stat -- get file status
SYNOPSIS sys stat; name; buf / stat = 18.
DESCRIPTION name points to a null-terminated string naming a
file; buf is the address of a 34(10) byte buffer
into which information is placed concerning the
file. It is unnecessary to have any permissions
at all with respect to the file, but all directo-
ries leading to the file must be readable.
After stat, buf has the following format:
buf, +1 i-number
+2,+3 flags (see below)
+4 number of links
+5 user ID of owner
+6,+7 size in bytes
+8,+9 first indirect block or contents block
...
+22,+23 eighth indirect block or contents block
+24,+25,+26,+27 creation time
+28,+29,+30,+31 modification time
+32,+33 unused
The flags are as follows:
100000 used (always on)
040000 directory
020000 file has been modified (always on)
010000 large file
000040 set user ID
000020 executable
000010 read, owner
000004 write, owner
000002 read, non-owner
