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). ...
CMake Error at /opt/cmake/share/cmake-3.20/Modules/CMakeDetermineSystem.cmake:203 (file): file attempted to write a file: /root/examples/chapter03/09-in-source/CMakeFiles/CMakeOutput.log into a source directory. 然而,它仍然创建了提到的文件!因此,我的建议是使用更旧的——但完全支持——机...

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 ...
// 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...
除了《静态分析C语言生成函数调用关系的利器——calltree》一文中介绍的calltree,我们还可以借助cflow辅助我们阅读理解代码。 cflow的说明和安装 cflow是一款静态分析C语言代码的工具,通过它可以生成函数的调用关系。和calltree不一样,cflow有独立的网页介绍它(gnu.org/software/cflow/#)。而且在Ubuntu系统上,我们可以...
