If you think about the problem (forget about the code, just think about the math), every single time that a lamp's id number is divisible by a number x, there will be another number, y, less than or equal to the number of lamps, by which it will also be divisible.

In my program, I am trying to use ioctl to turn on/off the wireless card, using SIOCSIFFLAGS (I am new to it but somebody said it is the most traditional way). However, it seems that I didn't set the flag correctly since the wireless is always on (I have root permission). If any one... (2 Replies)
