How can I let wavelan card inform my application about new accespoint information?

[Song.Lu-1]

hi,
 I am considering about using the wireless extension to get the access point information by event_driven way. So I read the source code of wireless extension implementation, wireless.c, and found the author used the ioctl means to assign the event handler. Am I right? Then I searched the  wireless applications for Linux in the  webpage : http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html and found most of them are applying the ioctl on the socket. It made me disapoint. Why? I have to bypass the socket because the transmission layer protocol which i need to implement is neither tcp nor udp.
So would you please give me some tips that if I want to bypass the socket to apply the ioctl on the driver for event_driven directly, how I can do it. For example, if the card detects there is a new signal of access point, then it send the information to the driver, then some event should be trigged to call some event handler.
Thank you very much!
