Any example about using DismProgressCallback?

[typenoob]

Here is my code to enable netfx3 features

import (
	"fmt"
	"syscall"
	"unsafe"

	"github.com/google/glazier/go/dism"
)

func callback(current uint, total uint, data unsafe.Pointer) {
	fmt.Println(current)
}
func main() {
	s, err := dism.OpenSession(dism.DISM_ONLINE_IMAGE, "", "", dism.DismLogErrorsWarningsInfo, "", "")
	if err != nil {
		panic(err)
	}
	defer s.Close()
	path := "./sxs"
	name := "NetFx3"
	n, err1 := syscall.UTF16PtrFromString(name)
	if err1 != nil {
		panic(err1)
	}
	progress := callback
	err2 := dism.DismEnableFeature(*s.Handle, n, nil, nil, true, &path, 1, true, nil, unsafe.Pointer(&progress), nil)
	if err2 != nil {
		panic(err2)
	}
}

which returns errors

Not set Progress parameter would solve it, but I hope to use Progress Callback function, appreciate to any help.

[typenoob]

Not related to this issue, but I believe the the type of SourcePaths in the following function should be **uint16

glazier/go/dism/zdism.go

Lines 146 to 160 in 9e7cb89

	func DismEnableFeature(Session uint32, FeatureName *uint16, Identifier *uint16, PackageIdentifier *DismPackageIdentifier, LimitAccess bool, SourcePaths *string, SourcePathCount uint32, EnableAll bool, CancelEvent *windows.Handle, Progress unsafe.Pointer, UserData unsafe.Pointer) (e error) {
	var _p0 uint32
	if LimitAccess {
	_p0 = 1
	}
	var _p1 uint32
	if EnableAll {
	_p1 = 1
	}
	r0, _, _ := syscall.Syscall12(procDismEnableFeature.Addr(), 11, uintptr(Session), uintptr(unsafe.Pointer(FeatureName)), uintptr(unsafe.Pointer(Identifier)), uintptr(unsafe.Pointer(PackageIdentifier)), uintptr(_p0), uintptr(unsafe.Pointer(SourcePaths)), uintptr(SourcePathCount), uintptr(_p1), uintptr(unsafe.Pointer(CancelEvent)), uintptr(Progress), uintptr(UserData), 0)
	if r0 != 0 {
	e = syscall.Errno(r0)
	}
	return
	}
