Question

I am trying to use _CrtDumpMemoryLeaks() to display memory leaks in my program.

But it does not display anything except for returning 0 in case of no memory leaks and 1 in case there is a leak.

The link here shows the output should be like:

Detected memory leaks!
Dumping objects ->
D:\VisualC++\CodeGuru\MemoryLeak\MemoryLeak.cpp(67) : {60} 
normal block at 0x00324818, 4 bytes long.
Data: <,   > 2C 00 00 00 
Object dump complete.

Can anyone suggest the correct way of using this function.

Download the sample from the following link. You have to set the following parameters to direct output to console.

   // Send all reports to STDOUT
   _CrtSetReportMode( _CRT_WARN, _CRTDBG_MODE_FILE );
   _CrtSetReportFile( _CRT_WARN, _CRTDBG_FILE_STDOUT );
   _CrtSetReportMode( _CRT_ERROR, _CRTDBG_MODE_FILE );
   _CrtSetReportFile( _CRT_ERROR, _CRTDBG_FILE_STDOUT );
   _CrtSetReportMode( _CRT_ASSERT, _CRTDBG_MODE_FILE );
   _CrtSetReportFile( _CRT_ASSERT, _CRTDBG_FILE_STDOUT );
