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.

shyam
