Sorry for bothering you all again.
I ask yesterday for some help with the dev_ioctl function. Because nobody
answered I send it again with the source code of the function which should
read the name from the wireless device. The function is called from another
module with the device_name eth0.
The problem is that sometimes I get "no wireless extension" but if a packet
arrive (e.g. Router solicitation) I can read the wireless settings.
Is there anything I forgot ?
Do I need locking functions or is it not possible to use the dev_ioctl
function from another kernel module ?
void mho_get_wireless_info(char *dev_name)
{
struct iwreq wrq;
/*set the device name*/
strncpy(wrq.ifr_name, dev_name, IFNAMSIZ);
if( dev_ioctl(SIOCGIWNAME, &wrq) < 0)
{
printk("MHO: No wireless extension. error = %d\n",err);
return;
}
else
{
printk("Wireless info: devicename= %s \n",wrq.u.name);
return;
}
}
Thank you for all help in advance
Jörg
