Hello All,
I have freed the memory which was allocated using malloc.
Is there any utility or function in C to check whether the memory is freed or not.
int *a;
a=(int *)malloc(2*sizeof(int));
a[0]=1;
a[1]=2;
free(a);
Even after free function the value of a[0] and a[1] is same (i.e 1 and 2).
I am using Turbo C. I have doubt whether memory is freed.
Thanks in advance.

Just because you free memory doesn't mean it doesn't exist anymore. It depends on the OS and the heap. For example, heaps often cache blocks that have just been free to be recycled if a compatible request comes in soon after. Let your heap do its thing and trust in its wisdom.

Actually memory is free & goes to OS free mamory heap. But ur pointer still point that memory address. U can read that address. But if u want to write something that exception is generate.
For further conferation allocate same amount of mem after free some mem. OS allocate same mem block for that. A before free if u allocate then provide different mem block.

That's not necessarily true. For example, on x86 Windows the CPU, and therefore the OS, can only map memory around in 4K chunks. Another way of saying this is that on Windows (x86) the page size is 4K. This means that if you use a low level memory allocation function (like VirtualAlloc) the minimum allocation size is 4K. Getting around this limitation is one of the main functions of the heap (whether it's the Win32 heap accessed with functions like HeapAlloc or a custom heap layered over HeapAlloc or implemented in terms of VirualAlloc). When you attempt a small allocation from a heap (less then 4K on Windows) the heap gets a page of memory (if it hasn't already gone one handy) and hands you part of it. If another small allocation occurs it will hand out another piece of this same page (or some other partially used page) until the whole page is full and then it will get another page and start over. In short, just because you free some memory from a heap doesn’t mean the page that contains that address is freed as other allocations may reside in the same page: only when all allocations on a particular page are freed can the heap release the physical memory (and it may still not do so straight away). The OS can’t efficiently arrange for an exception to be generated when you access the unused part of a page as the underlying hardware only supports setting the memory protection attributes for a whole page. The real situation is even more complex than this brief description: for example the heap can recycle a heap block (and thus not free it) even when it contains no allocations as a form of caching and it need not change the protection on the page (so an exception is generated on access) as doing so means a context switch to Ring-0 and then another back to Ring-3.
