下面的例子: static int add (int a, int b); static 修饰的 function 表明这个函数只对于当前文件中的其他函数是可见的, 其他文件中的函数不能够调用. 关于变量. 使用 static 和 extern 修饰变量的时候, 变量的生命周期是一样的, 不同的是变量的作用域. 一个表格 2010-7-14 2013-11-8 · extern的用法 1.extern修饰变量 1.1 同一个变量被多个文件共享时，就要注意申明为extern int a；形式，在XX.h文件中先声明为extern int a；后在相应的.cpp文件中定义注意还是extern int a =200；，其他文件若要引用该变量，就可以在其.cpp文件中包含#include extern这个关键字的真正的作用是引用不在同一个文件中的变量或者函数。 2020-10-20 · int x; // definition x is 0 extern int y; //y defined in elsewhere extern char c = ‘ g ’; // definition ,c is initialized 如果要在多个文件中使用外部变量，只需在一个文件中包含该变量的定义（ORD）,但在使用改变量的其他所有文件中，都必须使用extern声明这个变量。 2016-8-1 · 还有一点是，extern int v可以放在a.c中的任何地方，比如可以在a.c中函数func ()定义的开头处声明extern int v，然后就可以引用到变量v了，只不过这样只能在func ()作用域中引用变量v (这还是变量作用域的问题，对于这一点来说，很多人使用时都心存顾虑，好像extern声明只能用于文件作用域似的)。 2014-3-27 · 1 extern int * extern_array; extern_array的内容实际上在Link处理完之后，竟然变成了extern_array []首地址。. 也就是说在另一个文件中通过extern_array [index] (也就是* (extern_array + 1))，.

A: An extern array of unspecified size is an incomplete type Typically, this is used in a header file for a variable that will be defined in a separate implementation file. // global scope int x; // definition; x will be default- initialized 'extern int' only tells the compiler that there is a variable somewhere else in your code but nothing more. So you need to define it somewhere External/global variables have file scope and static storage duration.

External variables are always reinitialized immediately before the OnInit () is called. extern int *a , int a[10]. C / C++ Forums on Bytes. Army1987 Applied to a function declaration, the extern keyword in fact does nothing: the declaration extern int incr (int) is exactly the same as int incr (int). This is because all function declarations have an implicit extern applied! The extern modifier is used to declare a method that is implemented externally. A common use of the extern modifier is with the DllImport attribute when you are using Interop services to call into unmanaged code. In this case, the method must also be declared as static, as shown in the following example:
The extern storage class specifier can modify a declaration in one of the three following ways, depending on context: It can be used to declare a variable without defining it. Instead, it simply points to the global variable defined in the other file. extern volatile int IOstate; // declaration of IOstate Declaration must include any qualifiers used in the definition. Now this header file can be included to C source files that need to access this variable:

Instead, it simply points to the global variable defined in the other file. extern volatile int IOstate; // declaration of IOstate Declaration must include any qualifiers used in the definition.
