Next() is not working

[DryreL]

I was planning to get GPUs count.

Created a function:

`int GetGPUsCount()
{
// Call the function to initialize ADLX
if (!InitializeADLX())
{
// ADLX initialization failed, return a default value or handle the error
return -1;
}

// Get GPU list
IADLXGPUListPtr gpus;
ADLX_RESULT res = g_ADLXHelp.GetSystemServices()->GetGPUs(&gpus);

if (ADLX_SUCCEEDED(res))
{
    // Iterate through the list to count GPUs
    int gpuCount = 0;
    while (gpus->Next())
    {
        gpuCount++;
    }

    // Clean up ADLX before returning
    g_ADLXHelp.Cleanup();

    return gpuCount;
}
else
{
    // Handle the error, you might want to log or throw an exception
    std::cerr << "Failed to get GPU list" << std::endl;

    // Clean up ADLX before returning
    g_ADLXHelp.Terminate();

    return -1;
}

}
`

But Next() is not available. What should I use?

Does your system have AMD GPU installed? The GetGPUs will only return the AMD GPU.

I personally don't have AMD GPU but my friend has. I'm developing a plugin for Unreal Engine, it will get all hardware informations from the available GPU Brands. AMD is one of them.

I was going to test it on my friend's PC but Next() function is not available. It's not about if I have AMD GPU or not.

I'm not planning to run on my PC, but it must compile succesfully.

Hi,

To loop through any ADLXList, you can use the Begin() and End() methods.

int gpuCount = 0;

for (adlx_uint itr = gpus->Begin(); itr != gpus->End(); itr++) 
{
    gpuCount++;
}

However, for your example, you could use the Size() method:

adlx_uint gpuCount = gpus->Size();

Thank you!
