# Use unexported variables ## The unexported variables `unexport/i.go` ``` package unexport var i int func init() { i = 2 } ``` ## The new variables points the unexported variables `main.go` ``` package main import ( "fmt" _ "unsafe" _ "unexport" ) //go:linkname I unexport.i var I int func main() { fmt.Println(I) } ``` # Use unexported functions ``` package main import ( "fmt" "github.com/alangpierce/go-forceexport" ) func main() { var timeNow func() (int64, int32) err := forceexport.GetFunc(&timeNow, "time.now") if err != nil { // Handle errors if you care about name possibly being invalid. fmt.Println(err) } // Calls the actual time.now function. sec, nsec := timeNow() fmt.Printf("%v %v", sec, nsec) } ```
