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 could write a wrapper function

void new_fwrite(a, b, c, d) {
    if (fwrite (a, b, c, b) != b) 
       throw exception;
}

and then replace all calls to fwrite with new_fwrite
