Detailed Description
A Concrete Class for Dynamic Memory Management.This is a coalescing memory manager. It allocates (possibly) large chunks of heap space and apportions it out as requested. It merges together neighboring chunks on each free().

Constructor & Destructor Documentation
| CArena::CArena | ( | size_t | a_hunk_size = 0 |
) |
: Construct a coalescing memory manager. `a_hunk_size' is the minimum size of hunks of memory to allocate from the heap. If a_hunk_size == 0 we use DefaultHunkSize as specified below.
| virtual CArena::~CArena | ( | ) | [virtual] |
The destructor.
| CArena::CArena | ( | const CArena & | a_rhs | ) | [private] |
Member Function Documentation
| virtual void* CArena::alloc | ( | size_t | a_nbytes | ) | [virtual] |
| virtual void CArena::free | ( | void * | a_vp | ) | [virtual] |
Free up allocated memory. Merge neighboring free memory chunks into largest possible chunk.
Implements Arena.
