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...
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...
and the function's address is never used, then the function's own assembler code is never referenced. In this case, GCC does not actually output assembler code for the function, unless you specify the option -fkeep-inline-functions. Some calls cannot be integrated for various...
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, ...
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...
Under the traditional GNU inline semantics, an "extern inline" function would never create an external definition, the same as inline *without* extern in C99. In C99, and "extern inline" definition is simply an external definition with an inline hint. In short, the meanings of inline with ...
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...
The values of the safe context have been refined to use "declaration-block", "function-member", and "caller-context" consistently. The speclets had used different phrasing for these terms, and also used "safe-to-return" as a synonym for "caller-context". This speclet has been updated to...
