balazske added a comment. It is a way of find some of the cases with the mentioned way of tracking what operations are allowed after what operations with or without error check, on a specific stream. Instead of a stream a symbol that is passed to the function at a specific argument can be used (to generalize for other than streams). If the code would work this way, the check to discover the "error check statement" is still needed, like now in the checker.
But I think it is no problem to say that the return value should be checked always (for the specific functions). The fact that a function has failed and the return value was not checked is in itself a bug and should not discovered only when a later function is called. This is not always possible. For example at `strtol` type of functions we can only find if the return value is checked for special error return value. A failing `strtol` may not cause any discoverable abnormal conditions later.
