This library was written by me as part of the C Programming unit at Bristol University. It is designed to simplify the process of managing memory in C.
Calls to malloc() are replaced via the C Preprocessor by a function that calls malloc(), then adds the memory address to an internal data structure.
This data structure is initialised with a call to newHeapList() and is series of linked lists which are each chained together by their initial node. This way, every call to malloc() adds a pointer to the most recent chain, which can then be iterated and deallocated using freeHeapList(). In order to simplify this process further, newHeapList() and freeHeapList() can be implicitly called using an AUTOFREE block as shown below:
int main()
{
AUTOFREE {
char* foo = malloc(20);
char* bar = malloc(25);
}
}
In the above example, foo and bar will be automatically deallocated when the containing AUTOFREE block exits. It should be noted that this library does NOT at this stage handle calls to reallocate()
