Compilation preprocessing is the initial step in the process of converting a C source program into an executable program. This step is done by the preprocessor (preprocessor). Before the source program is processed by the compiler, the preprocessor first processes the macro (macro) in the original program.C Beginners may have no concept of preprocessor, this is understandable: the General C compiler will be

C1 condition include As follows: Code # Ifndef main_h _ # Define main_h _ Other content # Endif When we see the header file, the function is to prevent this header file from being included multiple times. Repeated definitions occur when multiple include operations are performed. Therefore, you must use this definition in each header file. If you still don't know how to use it, you can see the standard header file of C, such as fcntl. h. 2. Conditional compilation As follows: Code # Ifdef _ deb

People who are new to MFC programming are often intimidated by various macro definitions and preprocessing commands generated by the MFC wizard. However, preprocessing and macro definition are a powerful tool in C language. They can be used for simple source code control, version control, warning, or some special functions.　　A classic exampleThe most classic example of using preprocessing and

Word2007 prompt Error "This error is usually caused by macro security settings" Every time you run Word, a prompt window appears-"This error is usually caused by macro security settings." If you know that the macro is from a source that you trust, you can change the

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 tables in functions, such: Void printf (const char * format ,...); Until recently, variable parameter tables can only be applied to real functions and cannot be used in macros. The C99 compiler standard has finally changed this situation. It allows you

I. OverviewZabbix supports many macros that are used in various situations. A macro is a variable that is identified by the following special syntax: macroUsing macros effectively saves you time and makes Zabbix more efficient.In a typical use, a macro can be used in a template. Therefore, the template's trigger may be named ' {host.name} ' mysql{#MYSQLPORT} port is down, please check! ”。When this template

Original address: http://blog.csdn.net/cp1300/article/details/7773239 when we write a program, we always add more or less statements such as printf to output debug information. But the printf statement has a very inconvenient place is when we need to publish a program to be a one to delete these statements, and once again, when the need to debug, these statements have to add, which brings us a great inconvenience, wasted a lot of our time, but also caused the inefficiency of debugging. Therefore

The execution process of inline functions is similar to the macro definition with parameters, but the processing of parameters is different. Macro definitions with parameters are not calculated, but replaced directly. Inline functions are functions first, which means that many of the functions are suitable for inline functions. That is, inline functions evaluate the parameter expressions first, Then pass th

The execution of an inline function is similar to a parameter macro definition, but the parameters are handled differently. The macro definition with parameters does not operate on the parameter, but instead, the inline function is the function, which means that many properties of the function are applicable to the inline function, that is, the inline function evaluates the argument expression first, and th

In C language programming, for a relatively large project, the use of the library will be more, if the design of a slight negligence, it may create a macro-defined conflict. An example of a project is that the two header file defines "isspace (CH)", and the two macro definitions are inconsistent, causing the entire project to fail to compile. The solution to this problem is to undefine the

In C ++, although using macros is not recommended, macros often provide us with some convenience, and there are indeed a large number of Macros in the existing code. Some people think that macros are the root cause of errors, because some strange code may appear after macros are expanded, so this article will summarize some methods to view the code after macros are expanded. 1. in Visual Studio 2005, select project Properties> Configuration Properties> C/C ++> Preprocessor, and select generate

0. PrefaceFrom the beginning of learning C language began to contact Makefile, consulted a lot of makefile information but always feel no real master makefile, if you write a makefile always feel very laborious. So deliberately using the blog to summarize the relevant knowledge of makefile, through examples to illustrate the specific use of makefile. The example says that makefile roughly divides into 4 parts 1. Only a single C file 2. Contains multiple C files 3. Need to include header file pa

In GNU C, a macro can accept a variable number of arguments, just like a function__va_args__ can be regarded as the ... Assign a value to the macro // Note you can't call ABC () #include #include #define ABC (...) printf (__va_args__) /* void ABC (...) {//printf (__va_args__);} */ int Main () {ABC ( " %s\n , " hello ); return 0 ;} Note that the m
