Function Type: Flushing Execution
This function destroys a window group given a screen_group_t instance. When a window group is destroyed, all windows that belonged to the group are no longer associated with the group. You must destroy each screen_group_t after it is no longer needed.
0 if the window group was destroyed, or -1 if an error occurred (errno is set).
