mail::ACCOUNT::getFolderIndexSize — Return number of messages in the current folder
        
        
        #include <libmail/sync.H>
        
        mail::ACCOUNT *mail;
| size_t messageCount=mail->getFolderIndexSize( | void); | 
mail::ACCOUNT::getFolderIndexSize returns
      the number of messages in the currently open folder. Messages
      in the folder are numbered starting with zero, and ending
      with one less than the number returned by this function.
For example, if mail::ACCOUNT::getFolderIndexSize returns 5
      it means that there are five messages in the folder, numbered
      0 through 4.
