How to log keyboard inputs in Keyboard Input Filter Driver (kbfiltr)

muneeb131 asked:

I am trying to store all the keyboard inputs being monitored using the kbfiltr driver (given in the Windows Driver Kit). At present, I can only create a text file using the ZwCreateFile routine, inside the DriverEntry routine; but I cannot write any information to file inside the KbFilter_ServiceCallback function. Please help me as to how I can save the intercepted keyboard packets in the log file.
