#include <strutil.h>
#include <cstdlib>
#include "sysutil.h"

        return os_platform::os_unix;
#else
        return os_platform::os_unknown;
#endif
    }

    std::string platform_name(os_platform type)
    {
        static std::map<os_platform, std::string> platform_map = {
            {os_platform::os_windows, "Windows"},
            {os_platform::os_macos, "macOS"},
            {os_platform::os_linux, "Linux"},
            {os_platform::os_unix, "Unix"},
            {os_platform::os_unknown, "Unknown"},
        };

        auto iter = platform_map.find(type);
        if (iter != platform_map.end())
        {
            return iter->second;
        }

        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
