Probing sooptcopyin()

[hiren panchasara]

I find sooptcopyin() failing and want to see how. 

Prototype is
int sooptcopyin(struct sockopt *sopt, void *buf, size_t len, size_t
minlen)

sopt->sopt_val seems to be the value passed in. But that being void *
type, I am not sure how to read it on fbt::sooptcopyin:entry invocation.
I've tried to cast it in a few ways without success along with
copyinstr/stringof.

Any pointers?

Cheers,
Hiren
