Hi

I want to create an array of vertex buffers using std::shared_ptr. How can set the deleter to the ::Release() member? I need this so I can InstBuffers.clear() before resetting the device.

for(int i=0;i<1024;i++){
		std::shared_ptr<LPDIRECT3DVERTEXBUFFER9> spNewBuffer(new LPDIRECT3DVERTEXBUFFER9/*, std::mem_fun_ref(IDirect3DVertexBuffer9::Release())*/);
		LPDIRECT3DVERTEXBUFFER9 pTempBuf = *spNewBuffer.get();

		hr = d3ddev->CreateVertexBuffer(BufferSize, D3DUSAGE_DYNAMIC, NULL, D3DPOOL_DEFAULT, &pTempBuf, NULL);

		if( hr!=D3D_OK ){
			MessageBox(NULL, L"Failed to make buffer", L"Error", MB_OK);
			return false;
		} else {
			InstBuffers.push_back(spNewBuffer);
		}
	}

Pass a function that calls Release as the second argument to the shared pointer.

std::shared_ptr<T> a(new T, [](T *ptr) {ptr->Release();});

I get a red line ..[](LPDIRECT3DVERTEXBUFFER9 *ptr){ptr->Release();}...

std::shared_ptr<LPDIRECT3DVERTEXBUFFER9> spNewBuffer(new LPDIRECT3DVERTEXBUFFER9, [](LPDIRECT3DVERTEXBUFFER9 *ptr){ptr->Release();});

Seems like shared_ptr dont like COM interfaces

std::shared_ptr<IDirect3DVertexBuffer9> spNewBuffer(new IDirect3DVertexBuffer9, [](IDirect3DVertexBuffer9 *ptr){ptr->Release();} );

Gives errors:

This seems to compile:

std::shared_ptr<LPDIRECT3DVERTEXBUFFER9> spNewBuffer(new LPDIRECT3DVERTEXBUFFER9, [](LPDIRECT3DVERTEXBUFFER9 (*ptr)){(*ptr)->Release();} );

Right, I get a runtime error when InstBuffers.clear();

Unhandled exception at 0x778815de in Game.exe: 0xC0000005: Access violation reading location 0xcdcdcdcd.

private:
	virtual void _Destroy()
		{	// destroy managed resource
		_Dtor(_Ptr);
		}

Should I just wrap everything in a class and release in the destructor, or do you have better ideas?

I want to create a shared pointer to the vertex buffer or shared pointer to the pointer to the vertex buffer.

The creation and attaching the actual buffer to the last pointer on the chain is done further down in code

d3ddev->CreateVertexBuffer(BufferSize, D3DUSAGE_DYNAMIC, NULL, D3DPOOL_DEFAULT, &pTempBuf, NULL);
