mex functions can return outputs:
void mexFunction(int nlhs, mxArray *plhs[], int nrhs,
const mxArray *prhs[]);
The nlhs : number of left hand arguments and plhs are the arguments you wish to return.
So you could return the status of the MAT file in plhs. You would call this function in MATLAB:
status = NameOfYourMexFunction(inputs);
