dear all,
    last time i asked a question "the STATUS command can't get correct reply",
and thanks for the Dan Williams's reply:

    i turn off the ap, and watch the info printed by wpa_suppliant, and 
as the Dan Williams said, the driver send a 
'disconnect'(CTRL_EVENT_DISCONNECT) event to the supplicant,  and i 
changed the driver, the problem is resolved. but i check the source 
code of wpa_suppliant, i can,t find the any code have 
CTRL_EVENT_DISCONNECT. so where is the associated code?

    BTW:the reason why i want to know the code because: i connect to 
the producter of the card,and he hopes to resolve the problem, so i 
need to know how the driver sends the event?
     best regards,
    belle
