Example #1

func copyVariant(p *syscall.Proc, source *types.Variant) (destination *types.Variant, err error) {
	err = errors.HResultToError(p.Call(
		uintptr(unsafe.Pointer(&destination)),
		uintptr(unsafe.Pointer(source))))
	return
}

Example #2

File: windows.go Project: jmptrader/com

func classIDFromProgramIDHelper(p *syscall.Proc, programID string) (classID *GUID, err error) {
	ptrProgramID, err := windows.UTF16PtrFromString(programID)
	if err != nil {
		return
	}

	err = HResultToError(p.Call(
		uintptr(unsafe.Pointer(ptrProgramID)),
		uintptr(unsafe.Pointer(&classID))))
	return
}
