Hi...
I need to write a C program that will accomplish these things:
- read the name of a block device from the command line (e.g. myprog
/dev/sda)
- open that block device in raw mode, read only
- read a random block, discard, repeat (infinite loop)
A quick answer: the usual read() C function will serve you well. It
doesn't matter if you use it to read normal file or device, it's all
treated as file. Pls read "man 2 read" for further information.
Just out of couriousity, why do you need a C program to do that? can you
just do it by using "dd"?
regards,
Mulyadi
