Do you mean you want to log the call stack of your program?
Karrtik IyerSoftware ArchitectCommented:
We have used many techniques in past to get the log of exact flow of our program (trace of function calls and in what order they were called and also trace the inputs/outputs of each function call).

1> During debugging the code we have used one of Visual studio's debugging window call stack (Debugging ->Windows -> Call stack)
2> In primitive days of our development, we even logged every in/out of each function to a log file, using/creating simple object on stack as first line of each function which takes function name as its input in the constructor, and in this stack object's constructor and destructor we used to log the details to a file. Something like Fn name --> In and Fn name --> Out. We also used to write this log at a different log level so that every time this is not logged.Only if log level is set to certain value this shall be logged to reduce the load on logging.
3> In windows we have used techniques as discussed in the below article to dump the call stack at any point.

you need to initialize the static members in a cpp file. then create an instance of FunctionLog at begin of each function you want to log.

of course you could enhance the logging by passing more arguments. you also could have a variable argument logging by passing a std::ostringstream by reference as argument. that would allow like

void MyClass::MyFunction(int n, char * text)
{
        std::ostringstream oss;
        FunctionLog("MyClass::MyFunction", (((std::ostream &)oss) << "n = " << n << "  text = " << text));
        ....
}
