 Starting in the C++17 Standard, the `[[nodiscard]]` attribute specifies that a function's return value isn't intended to be discarded. If a caller discards the return value, the compiler generates warning C4834.
 
-To resolve this warning, consider why your code doesn't use the return value. Your use of the function may not match its intent. You can circumvent the warning by assigning the value to **`std::ignore`** or by using a cast to **`void`** (see [Warning C26457](code-quality/c26457.md)).

 This warning was introduced in Visual Studio 2017 version 15.3 as a level 3 warning. It was changed to a level 1 warning in Visual Studio 2017 version 15.7. Code that compiled without warnings in versions of the compiler before Visual Studio 2017 version 15.3 can now generate C4834. For information on how to disable warnings introduced in a particular compiler version or later, see [Compiler warnings by compiler version](compiler-warnings-by-compiler-version.md).
