2. If recommendation #1 above causes too much code clutter – restrict your “using namespace” usage to within the class or namespace defined in the header file. Another option is using scoped aliases in your header files as shown below. 2.如果建议1以上引起太多的代码混乱 - 限制你的“使用...
整个系统将不得不更加复杂,并且会在运行时浪费宝贵的周期在许多(可能达到数万).text、.data 和其他段之间跳转。 所以,我们将要做的 instead is take each section of the object file and put it together with the same type of section from all other object files. 这个过程称为Relocatable对于对象文件). ...
// clib.c void c_func() { // function definition in C } // main.cpp extern "C" { void c_func(); } 在这个例子中,c_func函数在main.cpp中被声明,可以在main.cpp中被调用。 这种方式可以让我们在C++代码中使用C语言的库,极大地扩展了C++的功能。 以上就是extern关键字的基本用法。在下一章...
你可以通过在嵌套目录中的 listfile 添加 project() 命令来实现。只是不要忘记用 cmake_minimum_required() 它前缀。 由于支持项目嵌套,我们能否 somehow 连接并排构建的相关项目? 外部项目 技术上可以从一个项目到达另一个项目,CMake 也在一定程度上支持这一点。甚至还有一个 load_cache() 命令,允许你从另一个...

The <time.h> header now defines the timespec type and the timespec_get function from the C11 Standard. In addition, the TIME_UTC macro, for use with the timespec_get function, is now defined. This update is a breaking change for code that has a conflicting definition for any of these ...
