Overview

Package dxgi provides low-level DXGI (DirectX Graphics Infrastructure) COM bindings for Windows.

DXGI provides functionality for enumerating graphics adapters, creating swap chains, and managing display output. This package uses syscall to directly call DXGI COM vtable methods, providing a zero-CGO approach to graphics programming on Windows.

Architecture

DXGI uses COM (Component Object Model) interfaces. Each interface is represented as a Go struct containing a pointer to a vtable. The vtable contains function pointers for all methods. 

type IDXGIFactory6 struct {
    vtbl *idxgiFactory6Vtbl
}

Usage 

lib, err := dxgi.LoadDXGI()
if err != nil {
    log.Fatal(err)
}

factory, err := lib.CreateFactory2(dxgi.DXGI_CREATE_FACTORY_DEBUG)
if err != nil {
    log.Fatal(err)
}
defer factory.Release()

adapter, err := factory.EnumAdapterByGpuPreference(0, dxgi.DXGI_GPU_PREFERENCE_HIGH_PERFORMANCE)
if err != nil {
    log.Fatal(err)
}
defer adapter.Release()

desc, err := adapter.GetDesc1()
if err != nil {
    log.Fatal(err)
}
fmt.Printf("Adapter: %s\n", desc.Description())

Error Handling

All COM methods that return HRESULT are wrapped to return Go errors. This package reuses d3d12.HRESULTError for consistency.

Memory Management

COM objects use reference counting. Call Release() when done: 

factory, _ := lib.CreateFactory2(0)
defer factory.Release()
