When you code reaches a certain complexity you have to stop and implement test benches on each unit file .. I take it you are not doing so.
At the moment you are treating the symptoms not the cause.
Put simply your
Should be known to work bug free because it passes your benchtest unit with clear use guideline API
One of the things writing the bench test unit does is makes you stop and think about possible errors because you try to bench test the errors.
Your bench test code should obviously include malloc failing and all memory writes should be checked for size in the benchtest. So put bluntly
your code is failing because you are failing to test properly.
For even larger projects especially if threaded it often becomes necessary to use a MOCK framework to actually cross test the units together.
Typical test frameworks are listed in the C section of List of unit testing frameworks - Wikipedia[^]
The more common ones are CMock, Ceedling and Unity.
Many memory problems come from inherent issue with pointers that lets you copy the reference to an allocated object without restriction, but then doesn't let these references track when someone deletes it. Neither indirection nor garbage collection can solve that. Instead, use smart pointers!
Smart pointers behave for the most part like normal pointers, but they also make sure that the allocated objects get released when they are no longer referenced. And not earlier!
GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them. (Fran Poretto)
My problem is that as I write larger and more complicated (C) programs, errors in manual memory management become much harder to find and more catastrophic, particularly if caused by memory corruption....I couldn't find a standard practice
Err...because you are going at it from the wrong end. You are trying to fix it after it happens rather than stopping it before it occurs.
You do the latter by strict care in your design and implementation.
Create design that strictly specify where allocations occur and where they are cleaned up.
Implement code that follows that and if you allocate something then BEFORE you do anything else implement, strictly, how it is cleaned up.
That also applies to how you use each pointer also. If you are code a piece of code and your are not sure how to use it, whether it is defined or what you can put in it, then you have already done something wrong.
Hi, I'm new to Socket Programming, I don't know how to create a NamedPipe Server and Client Application, Here My requirement is below
1.) Create multithreaded pipe server and pipe Client inter-process sample application VC++/MFC.
2.) Transfer unsigned Char arr dummy bytes to and fro pipe client.
3.) Result display in printf both side.
By using VC++ or MFC Classes,
I have CListCtrl and updating this control with love data using OnTimer(). But i want to select some rows and do furthur actions. But when i select the row, the selected color appears,but moment it updating using OnTimer(), the selected row color become normal. How can i keep the selection row visible always?
(and so on...) in your test.cpp source file.
An altrernative, available only with C++ 17 compliant compilers is to declare such variables inline inside the header file (see, for instance INLINE VARIABLES[^]).
Well I have over 50 classes there. All of them have base class the same.
Those functions (about 20 functions) are needed only for my one 5 level class (Class A5 : public A4) and two 6 level child classes ( Class A61 : public A5 and Class A62 : public A5).
Reason because I want to make one handler class which will use A5 class virtual functions and will handle A61 and A62.
