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

You can remove the warnings like this:

(void) fwrite ( ,,,, );

Addressing your main question, if any of the fwrite() calls fail, I'd guess that it doesn't make sense to continue, as the output is presumably corrupt. In that case, and as you tagged this C++, I'd throw an exception.
