Are you using hostapd for this or the IAPP functionality in a separate
program? Please do note that hostapd in the CVS version of Host AP
driver includes initial IAPP implementation that I'm going to use as the
basis for full IAPP implementation..

Please note that a newer version (draft 5) is already available.

IAPP specific code has been mostly implemented as an additional library of functions to be linked to the main HostAP .We are facing some problems while implementing this related to retrieval of STA information from HostAP.
By "HostAP", do you refer to hostapd daemon or the kernel driver? Could
you please describe what are the main design differences between your
and my implementation of IAPP?

I'm assuming you are linking your code with hostapd. In this case you
can use ap_get_sta() function to fetch station info based on MAC address
and sta->aid contains the association id allocated for that station (or
0 if AID has not yet been allocated). See CVS version of
hostap/hostapd/iapp.c and function iapp_process_add_notify() for an
example how to remove association on the old AP.
