Calling convention in C++/CLI

C++/CLI

Hi,
I've defined a function for a C++/CLI library:

extern "C"
{
	INT_PTR __cdecl brl_graphics_Graphics(int Width, int Height, int Depth, int Hertz, int Flags);
}

And this is the function that calls it, it's just a wrapper:

IntPtr BlitzMax::BlitzMax::Graphics(int Width, int Height, int Depth, int Hertz, int Flags)
{
	return IntPtr(brl_graphics_Graphics(Width, Height, Depth, Hertz, Flags));
}

When I call it from a C# application I get a AccessViolationException, for some reason in the disassembly it doesn't use cdecl calling convention:

push        dword ptr [ebp+10h] 
push        dword ptr [ebp+0Ch] 
push        dword ptr [ebp+8] 
mov         ecx,dword ptr [ebp-4] 
mov         edx,dword ptr [ebp-8] 
call        FFD595B8 

Thanks for helping in advance.
