Hi All,I am trying to access /dev/mem in my user process. I could not access because not a privileged access. I tried to use iopl(3) call in linux 2.6, but i am getting unresolved symbol for this. Is any other way to get access in user process. I am not sure how to solve this. Can you someone throw some light on this.if(iopl(3)){
fprintf(stderr, "Cannot get I/O permissions (being root helps)");
return -1;
}
if ((fd = open("/dev/mem", O_RDWR | O_SYNC)) < 0) {
fprintf(stderr, "Failed to open /dev/mem");
return -1;
}
