[Solved] C Programming fwrite on full drive [closed]

Question

If a write cannot be performed, fwrite() either returns a short item count (if some items have been written before an error occurred) or 0. fwrite() does not block if an error occurs. To differentiate and end-of-file condition from an IO error, use the feof() and ferror() functions.
