Do something with it instead. fgets can fail for many different reasons — some expected, some not expected. The return value tells you when this has occurred. The values subsequently returned by feof and ferror, along with the global errno variable, will tell you precisely what happened. iloveeclipse changed the title RV_RETURN_VALUE_IGNORED on method annotated with '@com.google.errorprone.annotations.CanIgnoreReturnValue' RV_RETURN_VALUE_IGNORED should not be reported for methods annotated with '@com.google.errorprone.annotations.CanIgnoreReturnValue' on Oct 26, 2017 iloveeclipse added the enhancement label on Oct 26, 2017 2014-03-11 · Wrong value returning from a function on C I am having problem understanding why its returning wrong value from a function.

A C++ program can be made easier to read and maintain by using references rather than pointers. A C++ function can return a reference in a similar way as it returns a pointer. When a function returns a reference, it returns an implicit pointer to its return value. This way, a function can be used on the left side of an assignment statement. For a detailed chart on what the different ctype functions return for each character of the standard ASCII character set, see the reference for the header. In C++, a locale-specific template version of this function exists in header . Parameters c Character to be checked, casted to an int, or EOF. Return Value In this article.

The problem is like below. C# 7 allows to discard return values and out parameters.

If you need it, you won't be able to write your code. If there is a special case which must be handled and must never be implicitly ignored, an exception should be thrown. This warning indicates the caller doesn't check a function's return value for failure.

If there is a special case which must be handled and must never be implicitly ignored, an exception should be thrown. C++17 standardized the "return value ignored business" with an attribute. Therefore, I hope that compliant implementations will always warn only when nodiscard is given, and never warn otherwise. Example: main.cpp [[nodiscard]] int f() { return 1; } int main() { f(); } compile: scanf() returns a value, and your original code was ignoring (not using) it. Your compiler has an option enabled asking for a warning whenever a result is ignored, so you're getting that warning ( not an error, unless you also have something like -Werror) Will the compiler be able to optimize and get rid of the return value in this situation, or not? ex: if I just have the line be expression.set("X", some_function(x)); but I might also call the same function and use its return value for something else in another part of the program.
