How to execute a DLL file using Golang?

Question

go

I made a DLL file with go build -o testdll.dll -buildmode=c-shared dllGo.go

dllGo.go:

package main

import (
    "fmt"
    "os"

)


func TestCalc(a, b int) int {
    return a + b
}

func main() {
    fmt.Println(TestCalc(7, 9))
    f, err := os.Create("working.txt")
    if err != nil {
        fmt.Println(err)
    }
    f.Close()
}

How do I execute a DLL from main.go?

main.go:

package main

import (
    "fmt"
    "syscall"
)

func main() {
    
    h, err := syscall.LoadLibrary("testdll.dll")
    if err != nil {
        fmt.Println(err)
    }

}

What do I need to do to "run" testdll.dll?
Sorry for this might be a dumb question.
