function和macro都可以在CMakeLists.txt文件中定义和调用。在调用时,function和macro的参数传递方式不同。function的参数传递采用传值方式,而macro的参数传递采用文本替换方式。 另外,function和macro的作用域也有所不同。在CMake中,function的作用域是局部作用域,而macro的作用域是全局作用域。这意味着在function中定义...
One pro of using the inline keyword is that you get a check of the types of the arguments via the function prototype. Using macros you get nothing like that, so macros are liable to create strange errors if you put things of the wrong type in them. (Not nearly as horrible as ...

cmake中的宏(macro)和函数(function)都支持动态参数 变量ARGC记录传入的参数个数 变量ARGV0,ARGV1,...顺序代表传入的参数 变量ARGV则是一个包含所有传入参数的list 变量ARGN也是一个包含传入参数的list,但不是所有参数,而是指macro/function声明的参数之后的所有传入参数 ...

宏(Macro)本质上就是代码片段,通过别名来使用。在编译前的预处理中,宏会被替换为真实所指代的代码片段,即下图中 Preprocessor 处理的部分。 C/C++ 代码编译过程 - 图片来自ntu.edu.sg 根据用法的不同,分两种,Object-like 和 Function-like。前者用于 Object 对象,后者用于函数方法。
