You are still missing to allocate space. This should be done with the malloc or the calloc command.

i did as u said the Segmentation Error is gone now. ioctl still returns -1

Code:
cmd1 =  malloc(550);

A similar post was found on this forum on which u replied but the post thread was short. just posting the link so that it may ring any bells in your mind?


ictl error - ENOTTY


i also have the same number 3 as return result of open() command and ioctl returns -1
