Macros with Arguments A simple macro always stands for exactly the same text, each time it is used. Macros can be more flexible when they acceptarguments. Arguments are fragments of code that you supply each time the macro is used. These fragments are included in the expansion of the macro ...
Macro arguments are completely macro-expanded before they are substituted into a macro body, unless they are stringified or pasted with other tokens. After substitution, the entire macro body, including the substituted arguments, is scanned again for macros to be expanded. The result is that the ...
The following examples of macros with arguments illustrate the second form of the #define syntax: // Macro to define cursor lines #define CURSOR(top, bottom) (((top) << 8) | (bottom)) // Macro to get a random integer with a specified range #define getrandom(min, max) \ ((rand()...
We can define a function like Macro, in which we can pass the arguments. When a Macro is called, the Macro body expands or we can say Macro Call replaces with Macro Body.Now, the important thing is that: How Macro arguments evaluate? - "Macro arguments do not evaluate before Macro ...
第三章: 利用Options和BOOL_ARGS增强脚本灵活性 (Enhancing Script Flexibility with Options and BOOL_ARGS) CMake提供的cmake_parse_arguments命令不仅支持oneValueArgs和multiValueArgs这两种参数类型,还支持OPTIONS和BOOL_ARGS,这两种参数类型在提高脚本的灵活性和用户友好性方面发挥着重要作用。本章将重点介绍OPTIONS...
with macros. (In C++, inline functions are often a preferred method.) However, macros can create problems if you don't define and use them with care. You may have to use parentheses in macro definitions with arguments to preserve the proper precedence in an expression. Also, macros may ...

The function versions of these macros have the same names as the macros except that the function forms begin with the letter “X.” They use the same arguments. Using the macro versions is slightly more efficient in C because it eliminates function call overhead....
