I/O Errors

Question Text​

Which of the following types of errors are unlikely to occur during an I/O operation?

Question Answers​

  • The current user does not have sufficient permisions to access a given file

  • There is not enough space left on the disk

  • The file offset has reached the end of the file when reading
  • Some data blocks in the filesystem are corrupted

Feedback​

We can always reposition the file offset within a given file with either a fseek() library call or an lseek() syscall, so this is not an error. The others are more difficult to manage, so can be regarded as errors.
