Using file BackendType and FixedStringPrompt creates file, but does not prompt for password

[jsoneaday]

I would like to prompt the user for a password during encrypted file creation, but using FixedStringPrompt does not do so. Using TerminalPrompt does not work as it causes an error "multiple-value keyring.TerminalPrompt("Please select a password") (value of type (string, error)) in single-value context"

func SetFileStore(fileSaveDir *C.char, fileName *C.char, data *C.char) *C.char {
	saveDir := C.GoString(fileSaveDir)
	// saveDir, _ := os.Getwd()

	ring, openErr := keyring.Open(keyring.Config{
		AllowedBackends:  []keyring.BackendType{"file"},
		FilePasswordFunc: keyring.FixedStringPrompt("Please select a password"),
		FileDir:          saveDir,
	})
	if openErr != nil {
		openErrStr := string(openErr.Error())
		returnErrStr := (*C.char)(C.CString(openErrStr))
		defer C.free(unsafe.Pointer(returnErrStr))
		return returnErrStr
	}

	dataStr := C.GoString(data)
	fileNameStr := C.GoString(fileName)
	setErr := ring.Set(keyring.Item{
		Key:  fileNameStr,
		Data: []byte(dataStr),
	})
	if setErr != nil {
		errStr := string(setErr.Error())
		returnErrStr := (*C.char)(C.CString(errStr))
		defer C.free(unsafe.Pointer(returnErrStr))
		return returnErrStr
	}

	fileItem, getErr := ring.Get(fileNameStr)
	if getErr != nil {
		errStr := string(getErr.Error())
		returnErrStr := (*C.char)(C.CString(errStr))
		defer C.free(unsafe.Pointer(returnErrStr))
		return returnErrStr
	}
	if string(fileItem.Data) != dataStr {
		returnErrStr := (*C.char)(C.CString("File was not found"))
		defer C.free(unsafe.Pointer(returnErrStr))
		return returnErrStr
	}

	result := (*C.char)(C.CString(""))
	defer C.free(unsafe.Pointer(result))
	return result
}
