NAME
chmod - change mode of file
SYNOPSIS
(chmod = 15.)
sys chmod; name; mode
chmod(name, mode)
char *name;
DESCRIPTION
The file whose name is given as the null-terminated string
pointed to by name has its mode changed to mode. Modes are
constructed by ORing together some combination of the fol-
lowing:
4000 set user ID on execution
2000 set group ID on execution
1000 save text image after execution
0400 read by owner
0200 write by owner
0100 execute (search on directory) by owner
0070 read, write, execute (search) by group
0007 read, write, execute (search) by others
Only the owner of a file (or the super-user) may change the
mode. Only the super-user can set the 1000 mode.

chmod (I)
DIAGNOSTIC
Error bit (c-bit) set if name cannot be found or if current
user is neither the owner of the file nor the super-user.
From C, a -1 returned value indicates an error, 0 indicates
success.
