Hello. I am trying to understand and modify a complex programs written by others. I found the function which I need to modify and would like to get a list of caller(s) to this function. Given that there are hundreds of files and classes, it would be ineffective to go through each file to search for the callers. Is there a good way to do that? I know that there are programs which display the relationships among classes graphically. Something like that for member functions would be great. I am looking for a solution without the use of a debugger. Thanks.
