在函数定义处写inline关键字,仅在声明处写inline不会起作用 (UPDATE:而且在声明处写inline还会造成一个警告 -inline function ‘void base::foo()’ used but never defined)。 ** 多文件调用内联:如果内联函数的定义不在本文件中(例如base.h声明了一个类,base.cc定义其的某个成员函数为内联,而在main.cc中...
When building the project, I get many warnings that say "inline function ___ declared but never defined":This is weird, because they are defined. For example, OAED_USB.h has a corresponding OAED_USB.c file that very clearly defines the "OAED_ShiftNAdd" function...
Declaration/Definition Location: An inline function is often declared and defined at the beginning of thestructure of C++ program, but it can also be defined inside a class or a structure. Function Call: After the function is declared, it can be called from other parts of the program. During...
class ForwardReference { int i; public: // call to undeclared function int f() { return g()+10; } int g() { return i; } }; int main() { ForwardReference fr; fr.f(); } You must be thinking that this will lead to compile time error, but in this case it will work, ...
Alright, never mind, then. 5) If somebody used too many inline function resultant in a larger code size than it may cause thrashing in memory. More and more number of page fault bringing down your program performance.By the time a program becomes so large that the OS needs to use swap ...
One and only one definition of every non-inlinefunction or variable that isodr-used(see below) is required to appear in the entire program (including any standard and user-defined libraries). The compiler is not required to diagnose this violation, but the behavior of the program that violates...
how the compiler decides to inline or not inline, if force inline is not specified. I always thought the compiler decides on code size in a function. But in this example, the code size of the function stays the same. We just add another function which is never actually called. So... ...
When to Use the Inline Function? Inline functions are very efficient and can be used in various areas of a program. But there are some cases where you can utilize the maximum features of these functions and extract the maximum output from them. Some of these cases are: Inline functions can...
