Call this static function to allocate memory.
static __declspec(allocator) void* Allocate(size_t nBytes) throw();
Parameters
nBytes
The number of bytes to allocate.
Return Value
Returns a void pointer to the allocated space, or NULL if there is insufficient memory available.

Allocates memory. See malloc for more details.
CCRTAllocator::Free
Call this static function to free memory.
static void Free(void* p) throw();
Parameters
p
Pointer to the allocated memory.
Remarks
Frees the allocated memory. See free for more details.

Call this static function to reallocate memory.
static __declspec(allocator) void* Reallocate(void* p, size_t nBytes) throw();
Parameters
p
Pointer to the allocated memory.
nBytes
The number of bytes to reallocate.
Return Value
Returns a void pointer to the allocated space, or NULL if there is insufficient memory.
Remarks
Resizes the amount of allocated memory. See realloc for more details.
