Re: combine Ada with MS VS C++

[ich_bin_elvis@hotmail.com]

Hi, After some testing we found out that the problem was that in our
C++ program we had an struct described below.

typedef struct tagpoint
{
	double   x;
	double   y;
} point;

and Angle is prototyped like

extern "C" double Angle(double x1, double y1, double x2, double y2);

We used it like this:

double vinkel1;
point p0,p1,p2,p3;

and we sendt the parameters to Angle in the form of.

vinkel1 = Angle(p0.x, p0.y, p3.x, p3.y);

we found out that we need to create temorary variabels and send them
instead is this realy neccesary? In Ada we uses Interfaces.C.double to
recive the parameters and return the ange. Any comment on this is
apreciated.
