CMake本身是一个工具集,由五个可执行的程序组成:cmake、ctest、cpack、cmake-gui和ccmake,其中cmake可以说是出镜率最高的明星级别程序了,它用于在构建项目的第一步,进行项目的配置、生成和构建项目的主要可执行文件的工作。其他的程序们ctest用于运行和报告测试结果的测试驱动程序,cpack用来生成安装程序和源包的...

istrstream类是从istream(输入流类)和strstreambase(字符串流基类)派生而来,ostrstream是从 ostream(输出流类)和strstreambase(字符串流基类)派生而来,strstream则是从iostream(输入输出流类)和和 strstreambase(字符串流基类)派生而来。 他们的继承关系如下图所示: 串流同样不是标准设备,不会有预先定义好的全局对象,所...
