Re: Accessing disk blocks from user space

i guess you just havta read block size no:of bytes using the read syscall
if ur block size is defined as
#define BLOCK_SIZE 1024
then to get a block just read(fd,buf,BLOCK_SIZE);

and u can lseek 1024 bytes to get to various blocks.

for the file size ... i think u may be stuck with 2GB size ....

Bijoy.
