SolveEquationCalcYProc

The SolveEquationCalcYProc function is an application-defined callback function that is used by C_SolveEquation. This function implements the function Y(X). C_SolveEquation solves equations of the form $Y(X) = \textrm{TargetY}$ where $Y(X)$ is this callback function and TargetY is a parameter of C_SolveEquation. This function is called repeatedly as C_SolveEquation searches for a solution.

Parameters

Data (IN)

The application defined value that was passed to C_SolveEquation.

X (IN)

The latest estimate of $X$.

lpCallBackStatus (IN/OUT)

Points to a int variable which determines whether the function has been calculated successfully.

When SolveEquationCalcYProc is called the variable has value stOK. If $Y(X)$ is successfully calculated then leave this variable unaltered. If you wish to cancel the calculation then you should set this variable to stOperationCancelled. If $Y(X)$ cannot be calculated you should set this variable to a value other than stOK to indicate why the calculation failed. You can define your own status constants with values above stUserDefinedError and use these.
