# ProxyAllocator::GetTotalFreed

```cpp
size_t GetTotalFreed() const override;
```

获取累计释放的字节数。

**参数：** 无

**返回：** 累计释放的字节数

**线程安全：** ✅

**复杂度：** O(1)

**示例：**

```cpp
#include <XCEngine/Memory/MemoryManager.h>
#include <XCEngine/Memory/ProxyAllocator.h>

IAllocator* sysAlloc = MemoryManager::Get().GetSystemAllocator();
ProxyAllocator proxy(sysAlloc, "TrackedAlloc");

void* p1 = proxy.Allocate(100);
proxy.Free(p1);

size_t totalFreed = proxy.GetTotalFreed();
printf("Total freed: %zu bytes\n", totalFreed);
```
