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 permissions 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.
