CRT Debugging Techniques

If you are debugging a program that uses the C run-time library, these debugging techniques may be useful.

In This Section

Using the CRT Debug Library
Describes the debugging support provided by the C Run-Time Library and provides instructions for accessing the tools.
Macros for Reporting
Provides information on the _RPTn and _RPTFn macros (defined in CRTDBG.H), which replace the use of printf statements for debugging.
Debug Versions of Heap Allocation Functions
Discusses the special Debug versions of the heap allocation functions, including: how the CRT maps calls, the benefits of calling them explicitly, how to avoid conversion, tracking the separate types of allocations in client blocks, and the results of not calling _DEBUG.
Writing Debug Hook Functions
Lists links to client block hook functions, allocation hook functions, allocation hooks and CRT memory allocations, and report hook functions.
The CRT Debug Heap
Provides links to memory management and the debug heap, types of blocks on the debug heap, using the debug heap, heap state reporting functions, and tracking heap allocation requests.
