Question

I have intermittent crashes occurring in my ActiveMQ libraries due to the way I’m using the activemq-cpp API. It’d be much easier to debug the issue if I could observe every function being called leading up to the crash. Are there any quick ways to trace the entry and exit of functions in a Visual Studio 2005 c++ multithreaded program?

Thanks in advance!

Use a Tracer object. Something like this:

 class Tracer { public:   Tracer(const char *functionName) : functionName_(functionName)   {     cout &lt&lt 'Entering function ' &lt&lt functionName_ &lt&lt endl;   }    ~Tracer()   {     cout &lt&lt 'Exiting function ' &lt&lt functionName_ &lt&lt endl;   }    const char *functionName_; }; 

Now you can simply instantiate a Tracer object at the top the function, and it will automatically print ‘exiting… ‘ when the function exits and the destructor is called:

 void foo() {   Tracer t('foo');    ... }
