In linux/netlink. h, some macros are defined to facilitate message processing. These macros include:
# Define NLMSG_ALIGNTO 4 # define NLMSG_ALIGN (len) + NLMSG_ALIGNTO-1 )~ (NLMSG_ALIGNTO-1 ))
The macro NLMSG_ALIGN (len) is used to obtain the minimum value not smaller than len and the byte align.
# Define NLMSG_LENGTH (len) + NLMSG_ALIGN (sizeof (struct nlmsghdr )))
The macro
1. Define a simple constant: Define a constant to facilitate modification. (do not add a semicolon to the end !)
# Define n 1000
It is equivalent to const int n = 1000, but slightly different. Define is a simple replacement instead of a quantity.
2. Define simple functions: Pay attention to the use of parentheses
# Define max (x, y) (x)> (y ))? (X): (y)
3. Define a single row macro: There are three main usage types.
1) The prefix ##or Postfix ## is

In the macro replacement section of the class function, # symbol is used as a preprocessing operator, which can convert the language symbol to the string. For example, if X is a macro parameter, # X can convert the parameter name into a corresponding string. This process is called strin

First remember the difference between the two. The difference between inline functions and macros is,
(1) macros are replaced by preprocessors, while inline functions are implemented through compiler control.
(2) inline functions can access private member functions of objects. inline functions are the most widely used in C ++ and should be used to define access functions.(This is why the default member function of a common class is inline)

I have just passed the hlist-related functions and macro definitions, and I have done some work here. I hope it will be useful for you to learn about Linux in the future.
/* The Linux linked list designer (think that double-ended double-chain tables (next, Prev) are "too wasteful" for hash tables ", therefore, we have designed a set of hlist data structures for hash table applications-a single-finger-header dual-loop linked list. The hlist header ha

For a final variable, whether it is a class variable, an instance variable, or a local variable, the final modifier is used when the variable is defined, and the initial value is specified when the final class variable is defined, and the initial value can be determined at compile time. So the final variable is essentially no longer a variable, but a direct amount.

static void Main (string[] args) {
The bold code in the above program defines four final variabl
A macro is a set of commands that can be applied with one click. They can almost automatically do anything you do in a program, or even perform tasks that you think are impossible.
Macros are programming, but you can use them even if you are not a developer, and you don't even need to know any programming knowledge. Most macros you can create in Office programs are written in Microsoft VBA (Visual Basic for applications) language.

Macro can be used to implement custom directives, by using custom directives, you can define a section of a template fragment as a user instruction, using the macro instruction syntax in the following format:.........In the above format fragment, the following sections are included:The Name:name property specifies the name of the custom directive and can pass in multiple parameters when using a custom direc
Some of the previous contents content as a student, rarely used, may be working to meet a little more, but the first comprehensive study still do not want to have something to fall, although not commonly used but at least have an impressionThen go to the third chapter "Macro __cplusplus"In code written in C and C + +, we often see the following declaration in the header file:#ifdef __cplusplus extern " C " {#endif // some code #ifdef __cplusplus} #
For example, I want to automatically delete an Excel form after March 2, 2013, and a macro called Macro1 in the table.
Specifically as follows:

Datee = #3/2/2013#
If Date > Datee Then
Activeworkbook.changefileaccess xlreadonly
