What is a good programming pattern for handling return values from stdio file writing functions

Question

I\'m working on some code that generates a lot of

ignoring return value of ‘size_t fwrite(const void*, size_t, size_t, FILE*)’, declared with attribute warn         


        

Answer 1

Why don’t you wrap the fwrite into a Writer object of some kind and throw an exception if fwrite() returns an error code? Easy to code, easy to use, easy to manage. IMHO, of course. :)
