A compiler does not consider the request to inline a function if it is recursive. Functions containing one or more static variables are not considered an inline functions by the C++ compiler. A compiler denies
The function must also be compiled as usual if the program refers to its address, because that can't be inlined. static inline function中是可以使用声明被static修饰的标识符或函数的,现在假设以下场景:有三个文件header.h, test.c, test1.c 。在header.h中包含了static inline funciton: f(),在f...
define是宏定义,typedef是重命名。 typedef int int_32; typedef void(*Func)(int); // Func为一个函数指针 #define PI 3.1415 // 宏定义没有; #define max(x,y) ((x)>(y)?(x):(y)) 作用域不同 typedef (1)如果放在所有函数之外,它的作用域就是从它定义开始直到文件尾; (2)如果放在某...
当一个定义为inline的函数没有被声明为extern的时候,其表现有点类似于gcc中extern inline那样(C99里面这段描述有点晦 涩,原文如下): If all of the file scope declarations for a function in a translation unitinclude the inline function specifier without extern, then thedefinition in that translation unit...
Note: According to the C standard, If an identifier declared with internal linkage is used in an expression (other than as a part of the operand of a sizeof or _Alignof operator whose result is an integer constant), there shall be exactly one external definition for the identifier in the...
(c))). This caused the second invocation ofincrementto return 6, hence the expression evaluates to 30. Any expression that contains side effects may affect the result when used in a macro, examine the fully expanded macro to check if the behavior is intended. Instead, if the inline ...
gcc对C语言的inline做了自己的扩展,其行为与C99标准中的inline有较大的不同。 1.1. static inline GCC的static inline定义很容易理解:你可以把它认为是一个static的函数,加上了inline的属性。这个函数大部分表现和普通的static函数一样,只不过在调用这种函数的时候,gcc会在其调用处将其汇编码展开编译而不为这个函数...

A member function can also be declared as inline function, use the inline keyword before function declaration and definition, if function definition is written outside of class. Example In the below example,square()andaverage()are the inline functions inside the class (with in the class). ...
