![]() ![]() This permits the actual tracing statement to be hidden from the source code. TRACED defines a function so that the first statement is always a printf of it’s own name, and that it’s currently being called. _VA_ARGS_ is a special macro introduced in C99 that allows variable arguments, similar to those in the stdarg.h header of the C standard library. Here, the macro TRACED takes the desired name of a function, and it’s variable list of parameters. ![]() A great example is trying to track when integers are added with + operator. ![]() You also have to think carefully whether the behavior or events you’re trying to trace are even going to be called. Despite being a low level language, complete access to everything isn’t given. However, there are limits to what can be traced in C++. The advantage of tracing, when done correctly, allows code to be written as if it were never intended to be traced, yet still has the added benefit if debugging is required. Meaning, tracing a particular function, should not be different than how a different function might be traced. However, this should be done implicitly as much as possible. The goal of tracing code in C++ is to write code that can emit desirable information at run-time. In this article, I will explain the benefits and advantages of tracing. Tracing happens at run-time, but it is configured and structured at compile time. This approach deals with embedding and including messages that can be printed to a console or written to a file, which gives information on how the code runs. The other way is tracing, also called debug messaging. This is a dynamic analysis method, it happens at run-time. This allows inspection into the way the heap of the process grows or shrinks over time. There are two ways of tracking memory usage in C++. ![]()
