To do the opposite (reading) you can use fscanf to get those three lines. I recommend checking the return value in case the lines don't follow the expected format. Since your records are not in any particular order you'll probably have to use a basic linear search. Read each record and decide if it meets the search criteria.

Not until you write it, no.
