mail::folder::hasSubFolders — Determine if the folder is capable of storing other folders
        
        
        #include <libmail/mail.H>
        
        mail::folder *folder;
| bool
            flag=folder->hasSubFolders( | void); | 
Some folders contain messages. Other folders contain other
      folder (subfolders). Some IMAP servers are capable of
      creating dual-purpose folders that contain both messages and
      other subfolders. The hasSubFolders indicates whether folder is capable of containing
      other folders (subfolders).
A true result indicates that
      folder is capable of
      storing other folders. It may not necessarily mean that
      folder actually
      contains any folders, it might very well be an empty
      folder.
Applications should interpret a true result to mean that the mail::folder::createSubFolder(3x)
      function may be used to create subfolders.
