Calling c function that return a string

Question

Hallo,
I found an example for calling void c function(http://zone.ni.com/devzone/cda/epd/p/id/1513). I could adapt the example and make the function return an integer. the code of the adapted function would look like this:
 int __declspec(dllexport) multiply(int number) {return number*3; }
But I have problems when I want to return a string. Does someone knows how I should do. I tried:
 char* __declspec(dllexport) say(int number) {return "hallo"; }  
but won't compile.

Answer 1

yes the question was  more a c question then a labview question. I found the solution anyway, the correct code in order to get string is:
_declspec(dllexport) char* testchar2();_declspec(dllexport) char* testchar2() {      return "hallo"; }
