Is there an example of how to pass a string as a parameter into a C++-MEX S-function in Simulink?

Here's a working example:
const mxArray* pArrayValue = ssGetSFcnParam(S,0);
const char* pCharArray = mxArrayToString(pArrayValue);
std::string string_1(pCharArray);
mexPrintf(string_1.c_str());
Make sure that you pass a char array as parameter in single quotes.
'Hello World'
not
"Hello World"
