virtual void PassPhaseInfo(
    _LONG_T phase
) = 0;

The PassPhaseInfo method has no return value.

The PassPhaseInfo method can be used to pass solver phase information to AIMMS. This method should be called when your solver switches from one phase to another. The passed information is used by AIMMS to update the Progress Window.

The PassProgressLines method is an alternative for the two methods PassProgressInfo and PassPhaseInfo, and provides more control. You should choose to pass progress information using either of the two approaches, you should not mix both.
