Hi,
I have the following simple DLL in c++ un-managed code;
extern "C" __declspec(dllexport) void ArrayMultiplier(float (*pointerArray)[3], int scalar, int length);
void ArrayMultiplier(float (*pointerArray)[3], int scalar, int length)
{
for (int i = 0 ; i < length ; length++)
{
for (int j = 0; j < 3; j++)
{
pointerArray[i][j] = pointerArray[i][j] * scalar;
}
}
}
I have tried writing the following wrapper function for the above in c#:
[DllImport("sample.dll")]
public static extern void ArrayMultiplier(ref float elements, int scalar, int length);
where elements is a 2 dimentional 3x3 array:
public float[][] elements =
{
new float[] {2,5,3},
new float [] {4,8,6},
new float [] {5,28,3}
};
The code given above compiles, but the program crashes when the wrapper function is called:
Wrapper.ArrayMultiplier(ref elements, scalar, length);
Please help me here, and tell me whats wrong with the code above, or how a wrapper can be written for a simple c++ function:
void SimpleFunction(float (*pointerToArray)[3]);
Thank you all in advance
