vmemleak's Introduction

VDream Memory Leak detector version 9.1

Project setting

For Qt User
- Open "vmemleak.pro", build and library(*.a or *.lib) file will be created.
- Include "vmemleak.pri" in your project file(*.pro).
For none Qt user
- Add all "h" anc "cpp" files in src folder in your project.

How to use

Include VMemLeakMgr(or vmemleakmgr.h), call vmemleak_mgr_start() to start memory leak detection and call vmemleak_mgr_stop() to stop memory leak detection.

[main.cpp]

#include <VMemLeakMgr>

int main()
{
  vmemleak_mgr_start();
  ...
  vmemleak_mgr_stop();
}

Include VMemLeak(or vmemleak.h) file where malloc, calloc, realloc, free, new and delete are used.

[test.cpp]

#include <VMemLeak>

void foo()
{
  malloc(4);
  calloc(256, 4);
  ...
  new int;
  new int[256];
  ...
}

If compiler error occurs where other header file is included, include VMemLeakCancel(or vmemleakcancel.h) before the header file.

[cancel.cpp]

#include <VMemLeak>
...
... memory leak detection
...

#include <VMemLeakCancel>
#include <list>
...
... no memory leak detection
...

#include <VMemLeak>
...
... memory leak detection
...
