Hello,


Some compilers can detect unused variables. Which tools can generate
warnings for ignored return values from function calls in a similar
way? How much can it help in static semantic checking and code
analysis for flaw detection?


How different are the options or pragmas to configure and control this
behaviour for safety checks?


Regards,
Markus
