An array of a fixed size within a C struct is a value (the same as in
Go), but C.GoString expects a pointer to a C.char. Try
`C.GoString(&p.hostname)`.
Not tested. Note that if hostname is not properly zero terminated,
your code will crash or misbehave.
(Automatic array decay applies to C code, but not in Go.)
