    1. COWhy don't you pull the whole line in with `getline` and then tokenize it with `strtok`?

    2. CODoes this compile without warnings? You should **really** test the outcome of relevant system call as there are `fopen()`, `malloc()` and `fscanf()`. Those provide very helpful information, escpecially in cases like this one, when something does not work as expected. It's free info and help so to say!

    3. COI'm missing the question here. Are you asking for a better solution (in which case be more specific about what you don't like about this one) or are you chasing some bug (in which case be more specific about the problem you are having).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
