Syntax

void RHIMapStagingSurface
(
    FRHITexture * Texture,
    FRHIGPUFence * Fence,
    void *& OutData,
    int32 & OutWidth,
    int32 & OutHeight,
    uint32 GPUIndex
)

Remarks

Watch out for OutData to be 0 (can happen on DXGI_ERROR_DEVICE_REMOVED), don't call RHIUnmapStagingSurface in that case.
