I'm trying to use FFF from within Visual Studio 2015 and VC++, and the example I tried (attached) does not want to compile. Here's the test file:

extern "C"
{
#include "driver.h"
#include "registers.h"
}
#include <stdint.h>
#include "CppUnitTest.h"
#include "fff.h"

DEFINE_FFF_GLOBALS;

FAKE_VOID_FUNC(IO_MEM_WR8, uint32_t, uint8_t);
FAKE_VALUE_FUNC(uint8_t, IO_MEM_RD8, uint32_t);

using namespace Microsoft::VisualStudio::CppUnitTestFramework;

namespace FFFTestProject
{		
	TEST_CLASS(UnitTest1)
	{
	public:
    TEST_METHOD_INITIALIZE(Init)
    {
      /*RESET_FAKE(IO_MEM_WR8);
      RESET_FAKE(IO_MEM_RD8);
      FFF_RESET_HISTORY();*/
    }
		
		TEST_METHOD(TestMethod1)
		{
			// TODO: Your test code here
		}

	};
}`

The FAKE_VOID_FUNC and FAKE_VALUE_FUNC macros are generating the following warning.

Warning C4003 not enough actual parameters for macro 'PP_ARG_MINUS1_N' FFFTestProject c:\temp\projects\ffftestproject\ffftestproject\unittest1.cpp 12

Trying to compile generates the following errors, all stemming from the FAKE_VOID_FUNC and FAKE_VALUE_FUNC macros.
