Windows Events are a potential replacement for TRACE macros, depending on your particular scenario. The code gets compiled into both Debug and Release configurations. Event tracing can then be dynamically enabled and disabled, displayed in real-time,.

Introduction

Writing our own trace utility is much important for complicated and complex applications. This is useful since C++ does not have the concept of GC (garbage collector) unlike C# or Java which automatically takes care of those issues. A good trace file can help a lot if you are trying to find bugs or hard to find memory leaks that often raise during the production of the application.

So what we need is an easy utility that detects the memory leaks in place when the application is run. That also finds out where exactly the memory leak are and how many bytes of memory are not freed.

Using the Code

Mainly, we wanted to rewrite the new function so that whenever new is called, it adds the trace and of course for delete, we have to remove the trace. Both the methods should be synchronous with each other. Failing to call delete will trigger memory leak.

For delete, this is supposed to be called:

For checking the results, we need a helper method that walks us through the memory leaks:

I have used a List to iterate walk the elements.

Take a look at the main function: instead of calling new char[len+1]; I am calling DEBUG_NEW. This will add the trace and delete will remove the trace.

I still can't find out if there was a way to call new instead of DEBUG_NEW directly.

Strictly speaking, you cannot have a trace statement within a macro, because the WPP preprocessor runs before the C preprocessor. One solution is to run the C preprocessor twice, but there is an even simpler solution: define optional PRE and POST steps to the trace macros.

For example, you might want an 'exit on failed' macro, such as

In this case, using PRE and POST forms of the macro makes this possible.

Define the function

In the source file, define the function, for example:

Define the macros

In a header file, add the following definition directives. Put them after the WPP_CONTROL_GUIDS definition and before the #include statement for the trace message header file.

Add formatting

You can make the trace messages easier to read by including formatting data in the header file. /traktor-pro-27-1-patch.html. This step is optional.

In this example, the begin_wpp config and end_wpp statements identify the configuration data in the header file for WPP.

Also, to notify WPP that there is configuration data in the header file, add the -scan parameter to the RUN_WPP macro that invokes the WPP preprocessor. For example:
