Question

I need to pass a byte array from NS Basic to a static C++ dll.

in NS Basic, I define the function like this to static dll.

Declare "Function myFunc Lib ""dllLib.dll""(ByVal data As Byte()) As Long"
Buffer = Array(0,1,2,3)

'call the function
myFunc(Buffer)

For this, I would like to know what should be the signature of the static C++ function?

Answer 1

long myFunc(unsigned char* buffer);

You may also need to pass in the size of the array a second parameter –

long myFunc(unsigned char* buffer, int size);
