Visual c ++Memory leakage detection-VLDTool instructions

I.VLDTool Overview

Visual Leak Detector ( VLD ) Is used Visual c ++ Free memory leak detection tool. He has the following features: You can obtain the call stack of the memory leak point. If you can, you can also obtain the file and row number of the memory leak point;   Obtain the full data of the leaked memory; You can set the Memory Leak report level, which is open-source and free of charge.

III.VLDInstall

Method 1:

Decompress the package to obtain VLD. H, vldapi. H, VLD. Lib, vldmt. Lib, vldmtdll. Lib, dbghelp. dll . Set . H Copy files Visual c ++ By default Include Directory . Lib Copy files Visual c ++ By default Lib Directory Dbghelp. dll Copy to yourProgramThe installation is complete.

Method 2:

VLD. h, vldapi. h, VLD. lib, vldmt. lib, vldmtdll. lib, dbghelp. DLL and other files. . h file and . lib copy the file to the directory where the project file you want to detect is located (only for this project), and dbghelp. DLL copy to the running directory of your program. The installation is complete.

4.ViewVCOutput Information:

"Warning: Visual leak detector detected meory leaks! "

 

5.If no memory leakage occurs, the output information is:

"No memory leaks detected"
