chmod() [1] takes as the second parameter a bitwise or-ed combination of
a series of values. If you look at chmod's man page ("man 2 chmod" on
the shell) you can see the following values for the group id (I have OSX
so the actual value may be different on your OS):

           #define S_IRWXG 0000070    /* RWX mask for group */
           #define S_IRGRP 0000040    /* R for group */
           #define S_IWGRP 0000020    /* W for group */
           #define S_IXGRP 0000010    /* X for group */

So you just have to OR them to accomplish your goal.
