Subject: [Bluez-users] Problem when cancelling connect

Hi all!

I'm trying to cancel a call to connect() (The one called by
BtOBEX_TransportConnect) using a SIGALRM signal. It works fine, but a
random subsequent call to hci_inquiry() or sdp_connect() causes a
segmentation fault. I've tried to restore the default signal handler and
closing the socket by hand, with no luck. Any idea about what is going on?

Thanks in advance

I forgot to mention I cancel the call to connect() using siglongjmp:

sigjmp_buf jmpbuf;

int sig_handler(int signo)
{
siglongjmp (jmpbuf, 1);
}

...

signal (SIGALRM, sig_handler);

alarm( MAX_CONNECT_TIME );

if (!sigsetjmp(jmpbuf, 1)){
BtOBEX_TransportConnect(handle, BDADDR_ANY, &bdaddr, channel)
alarm(0);
...
}
else{
signal (SIGALRM, SIG_DFL);
return -1;
}
