Changing ESSID

[leandroal at gmail.com (Leandro Sales)]

Hi list.
   How can I change the wireless access point via programming code in
maemo platform? I have the following piece of code that works
perfectly in my laptop, but when used in maemo, the wlan0 interface
disconnect but not reconnect to the new ESSID.
    Any suggestion? Thanks

Leandro.

int setEssid (char iface[6], char essid[IW_ESSID_MAX_SIZE]) {
	int soc;
	struct iwreq wrq;

	cout << "Changing Access Points...";
	strcpy(wrq.ifr_name, iface);
	wrq.u.essid.pointer = (caddr_t)essid;
	wrq.u.essid.length = strlen(essid)+1;
	wrq.u.essid.flags = 1;

	soc = socket(AF_UNIX, SOCK_DGRAM, 0);
	if (ioctl(soc, SIOCSIWESSID, &wrq) < 0) {
		printf("Error setting ESSID on %s: %s\n", iface, strerror(errno));
		close(soc);
		exit(-1);
	} else {
		cout << " done!\n";
	}
	
	return 1;
}
