内联函数宏(inline function macro)是一种特殊类型的宏定义,它的定义方式与常规宏定义略有不同,其语法形式为: 替换为: #define function_name(parameters) inline function_body 与常规宏定义不同,内联函数宏的参数列表需要用括号括起来,而函数体则需要用inline关键字进行修饰。例如,下面是一个简单的内联函数宏的...

以下使用GNU89的标准 1.内联的定义: 内联就是一个关键字inline加载函数定义处,告诉编译器在编译的时候请对这个函数调用的地方进行内联调用(这里说的请,编译器可以拒绝这个操作因为内联函数的失败) 2.内联函数的作用 内联是为了节约函数的调用开销而诞生的,我们在调用一
C - Any function, with the exception of main, can be declared or defined as inline with the inline function specifier. Static local variables are not allowed to be defined within the body of an inline function. The following code fragment shows an inline function definition: inline int add(i...
When an inline function is not static, then the compiler must assume that there may be calls from other source files; since a global symbol can be defined only once in any program, the function must not be defined in the other source files, so the calls therein cannot be integrated. Ther...

(1)Inline函数 在C++中,关键字Inline可以被加入到任何函数的声明中。这个关键字请求编译器用函数内部的代码替换所有对于指出的函数的调用。这样做在两个方面快于函数调用:第一,省去了调用指令需要的执行时间;第二,省去了传递变元和传递过程需要的时间。但是使用这种方法在优化程序速度的同时,程序长度变大了,因此需要...
In C: Why is so that only inline functions with internal linkage (ie declared with static) may reference (ie copy address, read, write, or call) a variable or function at file scope with static storage duration while other inline functions may not? c inline-functions Share Improve this que...
repetitive addition of the inline code will increase the size of your program in direct proportion to the number of times the function is called. And, obviously, the larger the function, the more significant the size increase will be. The resulting program runs faster, but now requires more ...
