C# cdecl callback?

[Josh]

Is there any way at all to declare a callback function in C# that uses the cdecl calling convention?

Try something like this.

 

[UnmanagedFunctionPointer(CallingConvention.Cdecl)]

public delegate void MyDelegate();

 

if using this you'll also want to look into Marshaling e.g.

 

Marshal.GetFunctionPointerForDelegate(Delegate d)

//Converts a delegate into a function pointer that is callable from unmanaged code.

 

Marshal.GetDelegateForFunctionPointer(IntPtr ptr, Type t)

// Converts an unmanaged function pointer to a delegate

 

I needed to use these when calling native functions from the engine.dll for my LEControl. It's how I finally got the GetSize and MakeCurrent Delegates to work properly. These function are under the System.Runtime.InteropServices namespace.
