Kernal Programming

Hi Swetha,
  I am expecting like real time sample for learning. here all posts are like to explain me what is driver and how to write the os kind of think. Ok now my point is i want to write the tool for control my USB port with some grand and protection based on the password. Can you explain how to do this by using C++. That tool should be active automatically when USB port getting connection with device and from that tool only i have to allow or denied the file transfer permission between the two devices.

Suresh,
If you got the pointer, please mark the correct answer and close the thread.

If you want to write a driver, this (and the links leading from it) is a good place to start:

Hi,

If you want to be a System Programmer, then your choice of language will be C, C++ & ASM [assembly]. And, you should aware of the compilers & linkers.

HI,
 actually till now i do not have any knowledge about driver/system programs. but i have little bit understand with OS. But i love system programs and networking related concepts. Thats the reason, i wish to switch. But i dont know, where i have to start?. How to make practice for that and how to work with real time environment? I dont like to do simple addition or calculator programs in that language. I wish to understanding beginigs from real world examples only. Is there any websites or real time exercise is available?

My feeling is, you should have bit knowledge of device level programming like writing drivers, etc and for that you need low level languages. C++ can be a good start.

And basics of OS and it's functionality is mandatory
