Feature Request: Hex of ioctl(2)'s Third Parameter.

[Ralph Corderoy]

Hi,

strace is very useful;  it cuts below whatever the userspace language is
and shows what's really happening.

I've a couple of suggestions.  First, if an ioctl's third parameter
looks like a memory address then optionally provide us with a few words
of memory from there on.  Whether that's a hexdump starting on a
separate line, or a ioctl(..., 0xaddress [0x..., 0x...]), I don't mind.
Perhaps the number of bytes/words could vary, like the length of strings
with -s.

I realise if may sometimes look like an address but not be one, or it
may be an invalid address, especially by the time the Nth word is
accessed, but that's for the reader to discern and it would still be
useful in some cases where one's being passed strace's output and can
start manually mapping the hex to the struct that particular ioctl
expects.
