// Create device LPDIRECT3DDEVICE9 pDevice = nullptr; D3D9CreateDevice(&pDevice, ...); // Render graphics ... // Release device if (pDevice != nullptr) { pDevice->Release(); pDevice = nullptr; }
// Initialize device LPDIRECT3D9 pD3D = nullptr; LPDIRECT3DDEVICE9 pDevice = nullptr; if (SUCCEEDED(Direct3DCreate9(D3D_SDK_VERSION, &pD3D))) { D3DPRESENT_PARAMETERS presentParams = ...; pD3D->CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, ..., &presentParams, &pDevice); } // ... // Release device if (pDevice != nullptr) { pDevice->Release(); pDevice = nullptr; } if (pD3D != nullptr) { pD3D->Release(); pD3D = nullptr; }In this example, a Direct3D 9 device and a Direct3D 9 object are created using the Direct3DCreate9 function. The device is then released using the Release() method along with the Direct3D object. The LPDIRECT3DDEVICE9 Release method is part of the DirectX SDK, a package library that provides developers with tools for developing games and multimedia applications for Windows platforms.
