How to determine MEX API version?

I have written some years ago a C shared library to use with Matlab.

I was using the MX_API_VER preprocessor macro to detect MEX API version,

#include "mex.h"
#include "matrix.h"

#if (! defined MX_API_VER) || (MX_API_VER < 0x07030000)
/*
 *      Compatibiliy with older version of MATLAB
 */
typedef int     mwSize;
typedef int     mwIndex;
#endif

Unfortunately, it seems that the MX_API_VER has disappeared from matrix.h in Matlab 2016a.

Is there another way to detect MAX API version ?

Regards.

I have a complicated macro to detect API version at compile time that I could post, but if you are only trying to deal with the mwSize and mwIndex stuff you can check for MWSIZE_MAX. E.g.,

#ifndef MWSIZE_MAX
    #define  mwIndex        int
    #define  mwSignedIndex  int
    #define  mwSize         int
#endif

I think your solution will be sufficient for my usage.

However, I was surprised to see that the following has disappeared from the matrix.h, when upgrading to 2016a.

#define MX_API_VER 0x7nnnnnnn

Many thanks for your quick answer.
