Function            Extendedtotal - total Extended memory installed

  Syntax              int Extendedtotal(void);

  Prototype in        ibm.h

  Remarks             detects the total amount of Extended memory
                      installed.

  Return value        returns the total Extended memory installed, in
                      Kbytes.

  Note                you should check for the presence of Extended
                      memory with isExtended() before using this
                      function. Calling Extendedtotal() when no Extended
                      memory is present can lead to unpredictable
                      results.

                      main()
                      {
                           printf("Total Extended Memory is %dK\n",
                                Extendedtotal());
                      }
