    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.

    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.
