Tool for detecting memory leaks
c, c++, memory-leaks, memory-management, unix
Solution
Such tools usually instrument the exeutable with their own code. for instance they replace every call to `malloc()` and `free()` with their own functions which allows them to follow every allocation.
In Visual Studio this can be done automatically using just the C Runtime Library using functions from the family of `_CrtDumpMemoryLeaks()`
Problem
How do memory leak detection tools like purify and valgrind work? How can I design and implement my own such tool?
