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

A macro definition can contain two operators: # And ##. # The operator converts a macro parameter to a string literal. It can only appear in the replacement list of macros with parameters. # Operators have a lot of usage. Here we will only discuss one of them. Suppose we decided to use the PRINT_INT macro as a convenient method during the debugging process to ou

Access using macro control program 3. Use Conditions in macros Access using macro control program 3. Use Conditions in macros In some cases, you may want to perform one or more operations in a macro only when the specified condition is true. For example, if a macro is used to verify data in a form, the correspondin

These two days a little bit of boost preprocessor library, found that the boost of the crazy people to use a variety of artifice to define a variety of data types and structure, but also in the above definition of subtraction and so on various operations, in the process of rapid browsing, but also targeted the very familiar with the various macro names: list,Cons,fold_left, Fold_right, estimates that these people have moved a lot of the features of fu

Raise questions: Zabbix monitors the file system through LLD. zabbix first discovers all file system names and types through discovery rule, as shown below: shell#zabbix_get-s127.0.0.1-kvfs.fs.discovery{"data":[{"{#FSNAME}":"/","{#FSTYPE}":"rootfs"},{"{#FSNAME}":"/proc","{#FSTYPE}":"proc"},{"{#FSNAME}":"/sys","{#FSTYPE}":"sysfs"},{"{#FSNAME}":"/dev","{#FSTYPE}":"devtmpfs"},{"{#FSNAME}":"/dev/pts","{#FSTYPE}":"devpts"},{"{#FSNAME}":"/dev/shm","{#FSTYPE}":"tmpfs"},{"{#FSNAME}":"/","{#FSTYPE}":"ext

This article comes from http://blog.ednchina.com/wangxing/160233/message.aspx Write a good C language. A beautiful macro definition is very important. Using a macro definition can prevent errors, improve portability, readability, and convenience. The following lists some mature software commonly used macro definitions ...... 1. prevent a header file from being re

, the advantage of this method is that you can print the expression content in a unified way. Similarly, the following macro can be defined to print the values of other expressions: # Define printc (expr) printf (" # Define printf (expr) printf (" # Define printd (expr) printf (" In the GCC compiler, two string constants can be connected to a new string. Strings are equivalent as follows: "123456" and "123" 456" Because # expr is essentially a string,

1 .# If you want to include a macro parameter in a string, ansi c can do this. In the macro replacement section of the class function, # use the symbol as a prefix. Processing Operator, which can convert the language symbol into a string. For example If X is a macro parameter, # X can convert the parameter name into a corresponding string. This process is call

In C ++ programming, functions (including inline functions) are generally in lower case, while macro-defined "functions" (macros with parameters) are often in upper case. The above sentence seems common, but failing to follow this sentence can easily lead to unexpected errors! Today, we will record a typical case: Because inline functions are very similar to macros, they are performed before the program runs. They both replace expressions with the fun

In C + + development often used in the definition of macro use "#" or "# #", the following is a simple description of the use of two symbols:Define in the # is to use the argument after the # as a symbol, simply to connect it as a string, # #连接前后2个符号, the define definition in the beginning of the "#" macro substitution is not expanded, the macro beginning with th

In some cases, you may want to perform one or more operations in a macro only when the specified condition is true. For example, if a macro is used to verify data in a form, the corresponding information may be displayed to respond to certain input values of the record, and the other information to respond to different values. In this case, you can use conditions to control the
