Should be just

type fiodgnameArg struct {
        Len     int32
        Buf     *byte
}

according to go tool cgo -godefs types_freebsd.go

@dmgk, What is the reason for your assertion that the padding isn't needed? The file was created by commit. It is possible that definition was incorrect (e.g., due to a copy/paste mistake) or, in the intervening six years, the definition has changed. Does the padding cause any problems?
