Doubt in major and minor numbers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi All,

I am reading chapter 3 in LDD3 i checked same topics in LDD2 so i got some confusions.According to my understanding
Major number is used by kernel to identify the driver i.e major number tells about driver .
Minor number is used by the driver module to know about the device which is using this module i.e minor number related to device number
can i any one please tell am i correct?
if wrong please explain me a bit more

Thanks
