Matlab function handle as a argument called by C?

The MATLAB function x = fmincon(fun,x0,A,b) has a function handle @fun, when it compiles into a DLL, the function form is mlx- or mlf- as follow:
mlxFmincon(int nlhs, mxArray *plhs[], int nrhs, mxArray *prhs[]);
mlfFmincon(int nargout, mxArray** X, mxArray** FVAL, mxArray** EXITFLAG, mxArray** OUTPUT, mxArray** LAMBDA, mxArray** GRAD, mxArray** HESSIAN, mxArray* FUN, mxArray* X_in1, mxArray* A, mxArray* B, mxArray* Aeq, mxArray* Beq, mxArray* LB, mxArray* UB, mxArray* NONLCON, mxArray* options, mxArray* varargin);
The problem is how can I call this function in the visual studio? Is it a way to use the function handle as a argument just like the function pointer in C? thanks.

You cannot directly call MATLAB functions, as function handles do not point to machine code. You need to ask the MATLAB Engine to evaluate the expression.

is there a way to pass c++ functions to fmincon?

No.
You might, however, be able to pass the function handle of a mex function or of something you have loadlibrary()'d
