is different from the same C type used in another.

Any C function (even void functions) may be called in a multiple
assignment context to retrieve both the return value (if any) and the
C errno variable as an error (use _ to skip the result value if the
function returns void). For example:

	n, err = C.sqrt(-1)
	_, err := C.voidFunc()
	var n, err = C.sqrt(1)

Calling C function pointers is currently not supported, however you can

type BitrotAlgorithm uint

const (
	// SHA256 represents the SHA-256 hash function
	SHA256 BitrotAlgorithm = 1 + iota
	// HighwayHash256 represents the HighwayHash-256 hash function
	HighwayHash256
	// HighwayHash256S represents the Streaming HighwayHash-256 hash function
	HighwayHash256S
	// BLAKE2b512 represents the BLAKE2b-512 hash function
	BLAKE2b512
)

	var _C_zero *C.mpz_t

and then replacing all instances of C.zero with (*_C_zero).

Cgo's most interesting translation is for functions.  If xxx is a C
function, then cgo rewrites C.xxx into a new function _C_xxx that
calls the C xxx in a standard pthread.  The new function translates
its arguments, calls xxx, and translates the return value.

Translation of parameters and the return value follows the type

	diag.Level

// String is a function declared in the pflag.Value interface
func (m *MessageThreshold) String() string {
