andF.48 Don’t return std::move(local)Both rules are very rigorous.T&&You should not use a T&& as a return type. Here is a small example to demonstrate the issue.// returnRvalueReference.cpp int&& returnRvalueReference() { return int{}; } int main() { auto myInt = returnRvalue...
那在C语言中return 首先会向程序宣告函数完成，另外将计算结果返回。C语言中函数也可以不返回内容（void...
Return Values Thevoidkeyword, used in the previous examples, indicates that the function should not return a value. If you want the function to return a value, you can use a data type (such asint,string, etc.) instead ofvoid, and use thereturnkeyword inside the function: ...
int value = 10; // returns an error - value is a const inside the expression auto decrement = [ value ]( ){ return --value; }; auto increment = [ value ]( ) mutable { return ++value; }; increment; // 11 尽管其他选项很少使用,但您可以在 cppreference.com 的 lambdas 页面上获得有...
implementing return-by-value semantics for objects, or are you referring to the case where the return type is actually declared as a reference? If the latter, OK; if the former, however, I say "not necessarily" (and for all I know, that may even be the case for the latter). Consider...
这些函数不返回值。_invalid_parameter_noinfo_noreturn和_invoke_watson函数不会返回给调用方,在某些情况下,_invalid_parameter和_invalid_parameter_noinfo可能不会返回给调用方。 注解 C 运行时库函数传递非有效参数时,库函数会调用一个无效参数处理程序,该函数可由程序员指定执行多项操作。 例如,它可能会将问题报告...

此属性仅应用到函数声明中所声明的函数名。若拥有此属性的函数实际上返回,则行为未定义。 若函数的任何声明指定了此属性,则其首个声明必须指定它。若函数在一个翻译单元中声明为带[[noreturn]]属性,而同一函数在另一翻译单元中声明为不带[[noreturn]]属性,则程序非良构;不要求诊断。
