Greetings,

Please help me with the following :

Where can I find what means exactly and how to use each of the second
argument of the ioctl() system call in Linux : FIOxxx (file IOCTL
requests), SIOxxx (socket IOCTL requests), TCxxx TIOxxx (terminal
IOCTL requests) ?

I did not find yet anything useful on Internet about this topic.

Thanks,
Alexandru Goia.
