Modes are constructed by ORing together some combination of
the following:
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) Error bit (c-bit) set if 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.
