passing array of structs from c# to regular dll
- by buzz
Hi there
I have a regular dll with the followign fucntion exported.
extern "C" __declspec(dllexport) int FindNearestStuff(double _latitude, double _longitude , LocationStruct * locations[])
LocationStruct is very simple
struct LocationStruct
{
long positionIndex;
long item;
};
I'm tryign to call it from c# using
[DllImport("myclever.dll", CharSet = CharSet.None)]
private static extern int FindNearestStuff(double _latitude, double _longitude,
ref LocationStruct [] locations);
Its all cool and funky and i can step into the dll function from the debugger.
Inside the dll the LocationStruct array is populated correctly and all is very good.
the problem i have is when it returns back from the dll, the LocationStruct array is not coming back with the data - just empty values...
what am i missing?
cheers
Buzz
