Printing inode as unsigned long long fixes the issue. The cast is necessary. Relevant standard: C18 §6.5.2.2 6 Details: 'ino_t' may (and will likely) be defined as 'unsigned long'. If you try to print an 'unsigned long' with "%llu" you will: - have Undefined Behavior (and a warning) if 'sizeof(long) < sizeof(long long)'. - have a warning if 'sizeof(long) == sizeof(long long)'. So if you want to use 'unsigned long long', you'll need to cast. Cheers, Alex
