Use of memory debugging tool valgrind
1. Overview of Valgrind The latest version of Valgrind is 3.2.3, which includes the following tools: 1. memcheck: Check memory problems in the program, such as leaks, out-of-bounds, illegal pointers, etc. 2. callgrind: detect program code coverage and analyze program performance. 3. Cachegrind: Analyzes the cache hit rate and loss rate of the CPU for […]

How to Use Valgrind to Detect Memory Leaks in C++
How to Use Valgrind to Detect Memory Leaks in C++ Memory leaks are one of the most annoying and hard-to-find bugs in C++. They can cause your program to crash, run slowly, or behave unpredictablely. Fortunately, there is a tool that can help you find and fix memory leaks easily: Valgrind. Valgrind is a suite […]
C/C++ memory leak checking tool – valgrind
1. Overview of Valgrind Valgrind is a set of open source (GPL V2) simulation debugging tools under Linux. Valgrind consists of a kernel (core) and other debugging tools based on the kernel. The kernel is similar to a framework (framework), which simulates a CPU environment and provides services to other tools; while other tools are […]
