Another big feature needed by APIs is data validation, making sure that the data is valid, given certain parameters. For example, that some field is an `int`, and not some random string. This is especially useful for incoming data.

Without a data validation system, you would have to do all the checks by hand, in code.

you should first check whether the call succeeded before checking the error
result. For example:

	n, err := C.setenv(key, value, 1)
	if n != 0 {
		// we know the call failed, so it is now valid to use err
		return err
	}

Calling C function pointers is currently not supported, however you can
declare Go variables which hold C function pointers and pass them
