Whenever aninlinefunction is added to or changed in a header file, every source file that uses that header must be recompiled. 在头文件中加入或修改inline函数时,使用了该头文件的所有源文件都必须重新编译。
So inline member functions should be declared and defined in the same header. In other words, the inline function should (not must) be placed in the header file instead of the cpp file. An identical definition for the function must exist in every translation unit that uses that line ...
In theory, using inline functions can make your program faster because they eliminate the overhead associated with function calls. Calling a function requires pushing the return address on the stack, pushing arguments onto the stack, jumping to the function body, and then executing a return instruc...
Local static variables and string constants used in an inline function are also considered to have ...
3) It may cause compilation overhead as if some body changes code inside inline function than all calling location will also be compiled. 4) If used in header file, it will make your header file size large and may also make it unreadable. 5) If somebody used too many inline function re...
The most efficient way to code an inline function is to place the inline function definition in a header file, and then include the header in any file containing a call to the function which you would like to inline. Note:Theinlinespecifier is represented by the following keywords: ...
In the simple C++ program, we begin by including the essential header file <iostream> for input-output operations and use namespace to avoid prefixing std:: tostandard library functions. Then, we define a function calledsum()with theinline keyword,indicating that sum() is an inline function....
A non-static inline function cannot define a non-const function-local static and cannot refer to a file-scope static. staticintx;inlinevoidf(void){staticintn=1;// error: non-const static in a non-static inline functionintk=x;// error: non-static inline function accesses a static variabl...
Assuming I have defined a function 'f' in header file and include the header in two different files: a.cpp and b.cpp. Like: void f() {} You'll get the following error when compiling (cl a.cpp b.cpp): b.obj : error LNK2005: "void __cdecl f(void)" (?f@@YAXXZ) already de...
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()中声明了静态变量a,在test.c 和test1.c中include了header.h,并且test.c 和test1.c作为两个不同的TU编译,那么test.c...
