MCQ: Which of the following Statements stands true for <strong>writing a file</strong>?

• B. The directory is searched for the appropriate entry, and the current-file-position pointer is re positioned to a given value.
• C. space in the file system must be found for the file and an entry for the new file must be made in the directory.
• D. We use a system call that specifies the name of the file and where (in memory) the next block of the file should be put. Again, the directory is searched for the associated entry, and the system needs to keep a read pointer to the location in the file where the next read is to take place.
