How does UnrealEngine thirdparty plugin working without GetProcAddress?

Question

I'm learning UnrealEngine from begining, and I found a miraculous phenomenon： the Unreal thirdparty plugin load a thirdparty dll file with "LoadLibrary" function and invoke the function in dll file without GetProcAddress！

here is the plugin code:

void FMyPluginModule::StartupModule()
{
    // This code will execute after your module is loaded into memory; the exact timing is specified in the .uplugin file per-module

    // Get the base directory of this plugin
    FString BaseDir = IPluginManager::Get().FindPlugin("MyPlugin")->GetBaseDir();

    // Add on the relative location of the third party dll and load it
    FString LibraryPath;
#if PLATFORM_WINDOWS
    LibraryPath = FPaths::Combine(*BaseDir, TEXT("Binaries/ThirdParty/MyPluginLibrary/Win64/ExampleLibrary.dll"));
#elif PLATFORM_MAC
    LibraryPath = FPaths::Combine(*BaseDir, TEXT("Source/ThirdParty/MyPluginLibrary/Mac/Release/libExampleLibrary.dylib"));
#elif PLATFORM_LINUX
    LibraryPath = FPaths::Combine(*BaseDir, TEXT("Binaries/ThirdParty/MyPluginLibrary/Linux/x86_64-unknown-linux-gnu/libExampleLibrary.so"));
#endif // PLATFORM_WINDOWS

    //the GetDllHandle function load the dll file with LoadLibrary API
    ExampleLibraryHandle = !LibraryPath.IsEmpty() ? FPlatformProcess::GetDllHandle(*LibraryPath) : nullptr;

    if (ExampleLibraryHandle)
    {
        // Call the test function in the third party library that opens a message box
        // invoke ExampleLibraryFunction exported in dll file without GetProcAddress!!!!
        ExampleLibraryFunction();
    }
    else
    {
        FMessageDialog::Open(EAppMsgType::Ok, LOCTEXT("ThirdPartyLibraryError", "Failed to load example third party library"));
    }
}

After load the dll dynamicly with GetDllHandle function, the plugin code invoke ExampleLibraryFunction just like implicit link, how's that working....
