a.cpp:14: Print result of f(): b.cpp:75: Enter f() b.cpp:95: Exit f() a.cpp:14: 1234
I really don't understand why you'd want this. And more to the point, I'm really curious how you could implement this in C++: // show what you want above. BOOST_LOG(app) << "result of f() " << f(); And finally, I don't know why you'd want the above. What if f() then calls g(), and so on, all this functions doing some logging. Would you actually prefer: a.cpp:14: result of f() [100 lines of other logged messages] a.cpp:14: 1234 To: [100 lines of other logged messages] a.cpp:14: result of f(): 1234 Best, John -- John Torjo, Contributing editor, C/C++ Users Journal -- "Win32 GUI Generics" -- generics & GUI do mix, after all -- http://www.torjo.com/win32gui/ -v1.6.3 (Resource Splitter) -- http://www.torjo.com/cb/ - Click, Build, Run!
