(A modern compiler can optimize across translation units, and so a function call may be inlined even though the function definition is in a separate translation unit, but these optimizations are expensive, aren't always enabled, and weren't always supported by the compiler) functions defined in...
In §6.7.4, "Function Specifiers", the inline keyword is defined: Making a function an inline function suggests that calls to the function be as fast as possible.[118] The extent to which such suggestions are effective is implementation-defined. And footnote (non-normative), but provides clar...
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...
However, the function can also be defined inside the class or a structure. Once you have declared the function, it can be called from other parts of the program. And when there is a function call to the function inline, the compiler simply replaces the call statement with the inline ...
the compile options are-std=c++20 -Wall -Wextra. tested with Clang 16 and Clang trunk at the time of writing. both of them emit error like: :6:13: error: inline function not definedinline void func(T) noexcept;^1 error generated. this source...
Hence you can only have such an inline defined in one compilation unit, and every other one needs to see it as an out-of-line function (or you'll get duplicate symbols at link time). extern inline will not generate an out-of-line version, but might call one (which you therefore ...
5) In c++, by default member function declared and defined within class get linlined. So no use to specify for such cases. 6) Your function will not be inlined in case there is differences between exception handling model. Like if caller function follows c++ structure handling and your inli...
(...) Making a function an inline function suggests that calls to the function be as fast as possible. The extent to which such suggestions are effective is implementation-defined. As far as I know there had been tons of effort invested into compilers so they can effectively make decisions ...
I've simplified things a bit; the actual function is more than 60 lines of code! But the basic idea is that the frame sends a WM_SETMESSAGESTRING message to itself, with the command ID as WPARAM. WM_SETMESSAGESTRING is an MFC-private message defined in afxpriv.h. It sets the text ...
Whether a call to an inline function uses the inline definition or the external definition of the function (6.7.4).J.2 Undefined behaviorA function with external linkage is declared with an inline function specifier, but is not also defined in the same translation unit (6.7.4)....
