define什么意思 define 定义一个标识符来表示一个常量。其特点是定义的标识符不占内存，只是一个临时的符号，预编译后这个符号就不存在了。用 #define 定义标识符的一般形式为：define 标识符 常量 //注意, 最后没有分号 define 和 #include 一样，也是以“#”开头的。
To give you a complete overview of this function, we included a special section that explains how the structures that are used by this function to define the actions are composed. In another section, we will explain the errors and possible solutions that the use of sigaction() can cause. Sy...

In this example, we use the strdup() function to duplicate a string. Then, we use the printf() function to display the “original” and “duplicate” string pointers in the command console. To do this, we include the “stdio.h” and “string.h” headers in our code and define the ...
