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" functio...
if a function is defined asinline, but never used or called within the same translation unit, it is discarded by the compiler (unless you compile with the-qkeepinlinesoption).
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...
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...
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, because...
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...
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)....

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...
