mail::account::logout — Disconnect from the server
        
        
        #include <libmail/mail.H>
        
        
        class myCallback : public mail::callback {
        public:
            void success(std::string msg);
            void fail(std::string msg);
        };
        mail::account *account;
| account->logout( | myCallback &callback ); | 
Close the mail account. The application should wait until
      either callback.success or
      callback.fail is called (not
      much of a difference, really, in both cases the mail::account object disconnects from the
      server). The disconnected
      method of the mail::callback::disconnect object,
      originally passed to mail::account::open, is also invoked.
The application must wait until callback's success or fail method is invoked. The success method is invoked when this request
      is succesfully processed. The fail method is invoked if this request
      cannot be processed. The application must not destroy
      callback until either
      the success or fail method is invoked.
callback's
        fail method may be invoked
        even after other callback methods were invoked. This
        indicates that the request was partially completed before
        the error was encountered.
In this case, however, there is no substantial difference
      between success and
      fail. mail::account::logout does not destroy the
      mail::account object, the
      object may be destroyed after either callback function is
      invoked.
