I am confused, how to use copy_to_user function. I
register a file thru module in /proc say test_proc.

i used copy_from_user function to copy data writtened
to the file test_proc and stored in static global char
array. now while reading back that file if i use
copy_to_user function then it gives me Fault, so i
used the snprintf() function to copy data in user
buffer.

Post the code, must be some kind of programming error.
