Re: Problem calling ioctl() on 32bit systems, works on 64bit

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256

On a follow up I have made a little C snippet to intercept
the ioctl() call.

On 64 bit:
Received fd=3, request=8837, pointer=0x7ffce86ac3b8

On 32 bit:
Received fd=3, request=8837, pointer=(nil)
