Function nvapi_sys::gpu::display::NvAPI_GPU_GetAllDisplayIds

pub unsafe fn NvAPI_GPU_GetAllDisplayIds(
    hPhysicalGPU: NvPhysicalGpuHandle, 
    pDisplayIds: *mut NV_GPU_DISPLAYIDS, 
    pDisplayIdCount: *mut u32
) -> NvAPI_Status

This API returns display IDs for all possible outputs on the GPU. For DPMST connector, it will return display IDs for all the video sinks in the topology.

Returns

• NVAPI_INSUFFICIENT_BUFFER: When the input buffer(pDisplayIds) is less than the actual number of display IDs
