The usual drill is:
1. Get the documentation on os.Open():
$ go doc os.Open
Notice what it returns in its 1st return value has the
type *File. Since it has no "pkg." qualifier it means
that name is defined in the same package.
2. So we now read the docs on os.File:
$ go doc os.File
...and see all of its methods there, inclusing Seek().
3. So we read the docs on it:
$ go doc os.File.Seek
