- For Qt user
- Open libvmemleak.pro, compile and build library files(*.a).
- Include vmemleak.pri in your project file(*.pro).
- For none Qt user
- Add all files in src folder in your project.
- Include VMemLeakMgr.
- 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 before 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 before the header file.
[cancel.cpp]
#include <VMemLeak>
...
... memory leak detection
...
#include <VMemLeakCancel>
#include <list>
...
... no memory leak detection
...
#include <VMemLeak>
...
... memory leak detection
...- Run the source code and you will get the following result.
