MAPI: API for wireless cards under Linux 提供wireless的API函数。大家可以通过这个程序

/*
*	API for wireless cards under Linux
*
*		Moustafa A. Youssef - MIND Lab '01
*
* This API works for any driver that supports wireless extensions (provided that the driver works correctly)
* For the signal strength measurements from all the access points, only the mwavelan_cs driver works (as far as I know)
