-l ,the access permission displayed for the such files
starts with letter 'c' ,but here the program written
is stored as normal file.
The program u have written has to be compiled as a kernel
module .as you are writing a device driover you have to create
the device file for that using mknod .b4 you do that get the device's
major no and minor no and the type of the device 'c' | 'b'
can anyone plz tell me how to make this sample code
for driver as special file and pile and how to link it
with kernel .
compile the code and insmod the testdata.o file which resulted
from the compilation. now try reading/writing/whatever from the device
