Re: RE: WLAN driver problem
Hi Robert,
The core file is not generating. The WLAN driver is terminating when i call MsgReceivePulse. It's not giving
any memory fault or bus error.
I tried whether it receiving any signals (SIGINT, SIGTERM, SIGHUP) but its not receiving any signal also. [driver am
developing has minimal feature (scan and associate)]

*******here 2nd time msgreceivepulse call is there. (but it neither fails nor it blocks)
wlan driver stops abruptly(if i hit return key it gives me shell)
