Re: How to read file in kernel module?



Hello,
   I want to read file in kernel module. can anybody
help me by giving code for that?
Also whats suitable way to do that in kernel /proc or
shared memory? what i want is to read and write a user
file frequently.

Hi linux lover . Reading or wriring a file from kernel is possible . But its not recomended . Its better to communicate with the kernel module using Copyto_User() function or write to a /proc buffer . Still if you want to access
the file from the kernel . The only possible way is to access the file is to use the underlying functions to open , read & write . I dont exactly remembre the function names . But everything starts with file_XXX . Search for that in www.
