Use of memory leak detection tool LEAKDIAG.

LeakDiag is a Microsoft tool to detect memory leak, the use of relatively simple

First to download a ftp://ftp.microsoft.com/PSS/Tools/Developer%20Support%20Tools/LeakDiag/

installed, the default is in C:/leakdiag.



Then write a test program to test
#include < stdio.h >
#include < windows.h >

int main ()
{
while (1)
{
char * c = new char [10];
printf ("%s", c);
Sleep (1000);
}
return 0;
}

Select Aaa.exe in LeakDiag
Then select Windows Heap allocator to track the use of Heap, start at start, wait a second to press log, and then stop
Will generate a log below the C:/leakdiag/logs

The key part is < leaks ver = "1.25.28.2201" >
< STACK Numallocs = "size" = "048" totalsize = "0240" >
< Stackstats >
< Sizestat size = "048" Numallocs = "a"/>
< Heapstat handle = "340000" Numallocs = "/>"
</stackstats >

Where the Numallocs is the number of allocations, size is each time allocated, frame is leak call stack
The stack here only shows binary, because symbol doesn't match.

Add the corresponding PDB file path to [Tools]-[option]-symbol search path to get < leaks ver = "1.25.28.2201" >
< STACK Numallocs = "size" = "048" totalsize = "0288" >
< Stackstats >
< Sizestat size = "048" Numallocs = "Modified"/>
< Heapstat handle = "340000" Numallocs = "Modified"/>
</stackstats >

The memory leak caused by Test.cpp line 8.
In addition, the log information generated by the above LeakDiag can be analyzed with Ldparser.
