Matlab Engine Library for Zero-Crossing Detection

Hi,

i am working with generated code from a simulink model (rapid simulation target) . Everything works fine so far, but i would like to access the "ssGetZcSignalName"-method which is defined in the simulink/include/simstruc.h folder. During compilation i receive an "undefined reference" error, because i don't know in which library the method is located.

At the moment i'm linking against the following libraries: m, mwsl_solver_rtw, mat, mx, ut and mwsl_fileio. I could find the method by searching every single file in the matlab bin folder, but that would be very tedious ;-). Can somebody tell me in which library this method is located?

I see it defined in simulink/include/simulink.c, which is supposed to be included in all S-functions by virtue of the lines:

#ifdef MATLAB_MEX_FILE    /* Is this file being compiled as a 
                             MEX-file? */
#include "simulink.c"     /* MEX-file interface mechanism */
#else
#include "cg_sfun.h"      /* Code generation registration 
                             function */
#endif

However, as you can see, it looks like maybe for the RSIM target, the S-function is probably not compiled into a MEX-file, so simulink.c is not included. Perhaps you need to contact MathWorks Tech Support to find out if you should be able to use ssGetZcSignalName in the RSIM target or not?
