A package compiled with cgo will include directives for both
internal and external linking; the linker will select the appropriate
subset for the chosen linking mode.

Example

As a simple example, consider a package that uses cgo to call C.sin.
The following code will be generated by cgo:

	// compiled by gc

	return 0, nil
}

func TestZeroReader(t *testing.T) {
	var z zeroReader
	r := NewReader(z)

	c := make(chan error)
	go func() {
		_, err := r.ReadByte()
		c <- err
	}()

	select {
	case err := <-c:
		if err == nil {
			t.Error("error expected")
		} else if err != io.ErrNoProgress {
			t.Error("unexpected error:", err)
		}
	case <-time.After(time.Second):

			Uname:    "rawr",
			Gname:    "dsnet",
			Format:   FormatGNU,
		}},
	}, {
		// BSD tar v3.1.2 and GNU tar v1.27.1 both rejects PAX records
		// with NULs in the key.
		file: "testdata/pax-nul-xattrs.tar",
		err:  ErrHeader,
	}, {
		// BSD tar v3.1.2 rejects a PAX path with NUL in the value, while
		// GNU tar v1.27.1 simply truncates at first NUL.
		// We emulate the behavior of BSD since it is strange doing NUL
