            }
    
            return "unknown";
        }
    } // namespace cutl

    4. 测试代码

    #include "common.hpp"
    #include "sysutil.h"
    
    void TestPlatformName()
    {
        PrintSubTitle("TestPlatformName");
    
        auto type = cutl::platform_type();
        std::cout << "OS platform: " << cutl::platform_name(type) << std::endl;
    }

    5. 运行结果

    ------------------------------------------TestPlatformName------------------------------------------
    OS platform: macOS
