// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// See Get Yahoo Mail OAuth2 Access Token for Desktop App 
// for sample code showing how to obtain a Yahoo Mail access token.

// In this example, our access token was previously saved to the following file which contains JSON like this:
// {
//   "access_token": "kCVQdnOdul...LHucA--",
//   "refresh_token": "AIenVXETSo0jklFBVkPS8vVm8E.Ej9ToRG.xDbDYmZ65WIs5t6CZhDrD",
//   "expires_in": 3600,
//   "token_type": "bearer",
//   "xoauth_yahoo_guid": "HGDQCVF5JB4YDOWHITQJFBHCWA"
// }

// The ListMailboxes method returns a Mailboxes object
// that contains the collection of mailboxes.
// It accepts two arguments: a refName and a wildcardedMailbox.

lcRefName = ""
// refName is usually set to an empty string.
// A non-empty reference name argument is the name of a mailbox or a level of
// mailbox hierarchy, and indicates the context in which the mailbox
// name is interpreted.

// Select all mailboxes matching this pattern:
lcWildcardedMailbox = "*"

// Draft
// Inbox
// Inbox/emailsWithAttach
