First look at the macro definition of __user: #ifdef __checker__# define __user __attribute__ (Noderef, Address_space (1)) As you can see from the macro definition, the __user macro definition is valid under the condition that you configure the __CHECKER__ macro, and it is obvious that the

Using these macro definitions, the self-describing capability of the program is greatly enhanced. The above example can be changed to: static unsigned short stopwatch [] ={S _ x _,S _ x,S _ x,S _ x __,S _ x

Replacing macros with Inline: 1. inline debuggable; 2. You can perform type security check or automatic type conversion; 3. Accessible member variables. In addition, the member functions defined in the class declaration are automatically converted to inline functions. Article (1) Inline functions and macro definitionsIn C, a commonly used pre-processing statement # define is used to replace a function definition. For example:# Define max (A, B) (a)> (

Macros: macro, preset text substitution mode:A macro is an abstract concept (abstraction) that replaces certain text patterns based on some of the predefined rules of a column, whereas an explanation or compiler automatically replaces this pattern when it encounters a macro.

You can use Word macro commands to increase your productivity when you edit a document using Word. By default, the security setting for Word macros is high, and macros are automatically disabled when you run the Word Macro command.

In fact, the use of macros is not difficult, the API has helped us do everything, we just focus on how to use the Get macro parameters and the return value of the macro An example: Import scala.reflect.macros.Context Import scala.collection.mutable.{ Listbuffer, Stack} object Qstringimpl { def qmap (P:char = int,elem:string): INT = Macro Qstringimpl.map_impl

a normal function declaration. We must define the function body. Inline tablefunction (int I) {return I * I }; Application of restrained functions: Application 1: define access functions for class member variables Inline functions are the most widely used in C ++ classes and should be used to define access functions. Generally, data members are defined as private or protected in the classes we define. In this way, the outside world cannot directly read and write the data of our class me
