define debug

In most cases, we can use breakpoints in vs.net to solve debugging problems. However, in some cases, you may need to manually output some information for debugging reference. Have you ever completed the debugging, forgot to delete an output

In gnu c, macros can accept variable parameters, just like functions, such:# Define pr_debug (fmt, arg ...)/Printk (KERN_DEBUG fmt, # arg) Use variadic macros to transmit Variable Parameter tables You may be familiar with Using Variable Parameter

Preprocessing commands in C #As a pair in Preprocessing: # Region name, # endregionIt may be the most widely used by everyone.CodeIn a long CS file, this is indeed a good way to make the code clearer. vs also uses this to automatically include the

Compiler built-in macros: First, we will introduce several built-in macro definitions of the compiler. These macro definitions can not only help us write cross-platform source code, but also help us output useful debugging information flexibly. The

Preface: When writing a program, we always add some printf and other statements to output debugging information, however, the most inconvenient part of the printf statement is that when we need to release a program, we need to delete these

In GNU C, a macro can accept a variable number of arguments, just like a function, such as: 12 #define pr_debug(fmt,arg...) \ printk(KERN_DEBUG fmt, ##arg) Passing variable parameter tables with variable-parameter

GCC supports complex macros, which use a different syntax so that you can give a variable parameter a name, like any other parameter, such as: Reference # define debug (format, args ...) fprintf (stderr, format, args) This definition is

Preprocessing commands in C #As a pair in Preprocessing: # region name, # endregion may be the most commonly used by everyone. I also use it to block code. In a long CS file, this is indeed a good way to make the code clearer. vs also uses this to

Programming nineth chapter Configuration and scheduling In the previous chapter, you learned how to create a common language runtime (CLR) component and how to use it in a simple test application. While the CLR component is ready to load, you should

I have learned C language and C ++ for three years, but I still don't know much about Conditional compilation commands. I can see some excellent source code on the Linux platform, such as uC/OS-II used a lot of compilation instructions, MFC also

Objective: When we write programs, we always add some statements like printf to output debugging information, but the printf statement has a very inconvenient place when we need to publish a program to delete these statements, and once you need to

[Problem description] generic is a special type that delays the work of a specified type until the client Code declares and instantiates a class or method. Generics are designed to solve function name conflicts. Generic is generally considered to be

The VC project must be consistent with the linked static library (*. Lib) file:For example: Does the Shared Mode use mfc dll or the static mode use mfc dll?Is it multithreading or a single thread? Is debug mode or release mode? Project property

#ifndef#define#endif的用法#ifndef#define#endif的用法  你所遇到的这几个宏是为了进行条件编译。一般情况下，源程序中所有的行都参加编译。但是有时希望对其中一部分内容只在满足一定条件才进行编译，也就是对一部分内容指定编译的条件，这就是“条件编译”。有时，希望当满足某条件时对一组语句进行编译，而当条件不满足时则编译另一组语句。     条件编译命令最常见的形式为：     #ifdef 标识符     程序段1     #else     程序段2

In general, all rows in the source program participate in the compilation. But sometimes it is desirable to compile a portion of the content only under certain conditions, that is, to specify a compilation condition for a portion of the content,
