If you run your app through Instruments, and there don't appear to be any memory leaks, you're with testing, you should be fine.

Hi all,
I'm working on tracking down some difficult to find memory leaks in my iPhone program. I'm running a quick test on an app which leaks an NSString object with the following intentionally -incorrect- code:

I think the reason you are seeing this in leaks input manager hacks before leak-hunting.
Crawl and see what piece of code caused the leak.

This doesn't cause any memory leakage.
My recollection is that, if you inspect the value, generally it is the same handle returned each time in your process (it may be different in a different process) .
You can call GetModuleHandle() all you want.

Hi,
I am trying to locate leaks using instruments, but the leaks I see there are like the ones in the next picture:

As you can see there's no information of which line of code is exactly leaking. All leaks I have, around 20, are like this, or in...

In order for an application to have no memory leaks, does the number of new in a C++ project match the number of delete?

If you are up to finding a preliminary way to detect memory leaks Purify to test for memory leaks n C++ programs.
For each new executed <=> no leak.

I'm running a debug build on the iPhone with Leaks. I'd like to break at certain points to see if particular leaks have occurred yet. This would allow me to narrow down where the leak is occurring by process of elimination. However, the debugger is ignored...

You can attach Leaks ....
Run in debug mode as usual, then run Leaks separately.
If you launch it in debug mode first (cmd-Y), you can then open Instruments and choose the Leaks template and attach to your running iPhone app process.

How do you fix a memory leak where you're returning from the function the leak itself?
For example, I make a char* returnMe = new char[24324]; returnMe is what ends up getting returned from the function. How do you account for this memory leak? How do...

It is not a memory leak, there's no leak.
You can still delete[] the pointer returnMe even after it is returned .

Hi,
I'm checking for leaks in Instruments, and I've set to check every second, but no leaks are appearing.
I'm sure there must be some in my app, is there anything which could stop these from appearing? Is there a good way I can create a leak so that ...

You're only going to find leaks with a tool ....
Creating a leak is easy:
id someObject = [[NSObject alloc] init]; someObject = nil;
Drop some code like that into your app, and you should definitely see a leak show up in Instruments.
