Return an error, respectively, in a language that supports it, raise an exception.
In my systems, nearly every call returns a status, and it is advisable to check this status. I had a number of long calls with windows programmers who complained about my system failing at some point, and most often, the reason was an ignored Non-OK status return at some point in the past.
Like "Your system loses the file I'm writing!". FileSystem_Open() returned a non-OK value (I don't remember the reason, but there was one). FileSystem_Write() returned a non-OK value (file pointer invalid). FileSystem_Close() returned a non-OK value (file pointer invalid). And he complains about a file that is not there...
