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 |
