Checking for memory leaks with Mtrace

http://blog.csdn.net/ixidof/article/details/6638066Memory leak Check method (for Linux)If you prefer to read the original document, refer to the "Allocation debugging" chapter of GLIBC info (performing info libc);GLIBC provides a way to check for memory leaks, provided that your program allocates memory using GLIBC's standard functions (such as malloc, alloc ...):1. call void Mtrace (void) at the beginning of the code that requires a memory leak check

Linux C Programming Memory leak Detection Tool (i): mtrace

ObjectiveAll programs that use dynamic memory allocation (allocation) have the opportunity to encounter memory leakage problems, and there are three common tools in Linux to detect memory leaks, including: Mtrace Dmalloc Memwatch 1. MtraceMtrace is the easiest to use among the three tools, Mtrace is a C function, declared and defined in void mtrace

Use mtrace in Linux for memory monitoring

Article Title: Use mtrace in Linux for memory monitoring. Linux is a technology channel of the IT lab in China. Including desktop applications, Linux system management, kernel research, some basic categories such as embedded systems and open-source systems may cause memory overflow and other problems when you write complex programs with many pointers. Debugging is also quite tiring. In fact, there is a tool in Linux that can be used for debugging. Thi
