Mastering C++ Multithreading

Basic use

Using Memcheck is fairly easy. If we take the demo application we created in Chapter 4, Thread Synchronization and Communication, we know that normally we start it using this:

$ ./dispatcher_demo

To run Valgrind with the default Memcheck tool while also logging the resulting output to a log file, we would start it as follows:

$ valgrind --log-file=dispatcher.log --read-var-info=yes --leak-check=full ./dispatcher_demo

With the preceding command, we will log Memcheck's output to a file called dispatcher.log, and also enable the full checking of memory leaks, including detailed reporting of where these leaks occur, using the available debug information in the binary. By also reading the variable information (--read-var-info=yes ...
