Hi,<br>
I have one structure called foo. Address of object of foo(say
objfoo) is passed to ioctl call<br>
<br>
status = ioctl(fd, arg, &objfoo);<br>
<br>
But during manipulation I am not getting ioctl error 5 (input/output
error).<br>
I am more confused about error in dmesg which is <br>
<big><big><b>foo: no-op </b></big></big><br>
<br>
What does no-op indicate? If it is no-operation, how can we relate
this to foo structure?<br>
<br>
Thanks,<br>
Pritam<br>
