In GNU C, a macro can accept a variable number of arguments, just like a function, such as:#define PR_DEBUG (Fmt,arg ...)/PRINTK (Kern_debug fmt,# #arg)passing variable parameter tables with variable-parameter macros (variadic macros)You may be familiar with the use of variable parameter tables in functions such a
Today, I mentioned the code comments in vs in a video from instructor Niu. There are a lot of comments on the Internet. I have also done this before, that is, how to follow the steps in a machine-like manner. I have never thought about more, so I have to repeat Baidu again this time. The connection address. The procedure is detailed.Two comments about vs: the code for template modification and the macro project for template modification. In my opinion, the first method is relatively rigid. From
I 've been procrastinating, playing with Lisp, but I can't solve this problem after all. In this case, I started to shake my mind.
The author first complained and compared the differences between lisp macros and other languages. Formally speaking, the so-called standard macros are the same as class libraries such as c and java, it is the stuff that has been completed and verified in advance and encapsulated

One challenge facing Access Services is to ensure that the logic behind various objects is portable between Access itself and the Access web database hosted by the SharePoint website. Use macros to implement logic in Access. Specifically, Access Services mea
In iOS development, macro definitions are often used, or some data types are modified with const, and often developers do not know how to use them correctly, resulting in the confusion of macros and const decorations in the project.Can you distinguish between the following? Do you know when to use it?#define Hscoder @ "Hansha haha"NSString *hscoder = @ "Hansha haha";extern NSString *hscoder;extern const NSString *hscoder;static const NSString *hscoder
ATL 7.0 introduces some of the new transformation classes and macros that provide important improvements to existing macros.The new string conversion class and name macro form: C Source type 2[c] target type [EX]which• The source type and target type are described in the following table.[c] is the target type must be read-only.[ex] is the initial size of the buffer that must be specified as a template parameter.

Macros do not follow the rules for scopes and types in C + +. This often leads to some subtle or less subtle problems. As a result, C + + provides a more suitable alternative to C + +, when it refers to C + + except for compatible C parts, such as inline functions, templates, and namespaces.
Consider:
#include "someheader.h"
struct S {
int alpha;
int beta;
};
If someone (unwisely) writes a macro called "alpha" or "beta", it will not
Tags: io ar using SP for file on Div CTIOgg macros, like macros in C, provide function encapsulation, which means that some configuration parameters can be organized into a macro and then shared across multiple parameter files, particularly useful for environments with complex or multiple replication points.

Because of this advantage, in the device-driven development, basically is to compile it into a dynamically loaded module. Note, however, that some modules must be compiled into the kernel, run with the kernel, never unloaded, such as VFS, Platform_bus, and so on.
So how does a C code implement both of these two ways?The answer lies in module_init macros. Now let's analyze the Module_init macros

Today we animate the method and technique of using buttons in Excel to invoke macros.
If the macro is valid for all workbook documents, we recommend that you add a command button on the toolbar to invoke the macro.
The operation method is as follows:
1. Execute the tools → customize command to open the Customize dialog box.
2. Switch to the Command tab, select Macros under Categories, and then drag the

ManyProgramThe clerk does not know what the "macro" in C really means? In particular, macros and functions are often confused when they have parameters. Here I want to talk about "macros". macros are just a definition. They define a statement block.

In the usual use of Word, you will always encounter the need to repeat the same content situation, when users can use the macro function to simplify a series of operations, thereby improving the efficiency of the instrument processing.
A macro is a well-defined operation, a collection of instructions, or a piece of program code. A macro is actually a series of commands and functions stored in a Visual Basic module that can be run at any time when it needs to be performed. Creating autorun
