vector of doubles - pinning

[Henrique]

Hi

Kind of newbie question:

We have a DLL with a function with a prototype like

void mult( int mtxhandle, double* x, double* y, int size );

where "size" is the size of both x and y vectors. What should be the correct
sintax to define its respective DllImport wrapper in order to use it (in C#)
like:

Double x[] = new Double[mysize];
Double y[] = new Double[mysize];

mult( handle, x, y, mysize );

Thank you

Henrique

Try this

[DllImport("mydll.dll")]
private static extern void (int mtxhandle, ref double x, ref double y, int
size);
