| 37 | * The MARK structure defines a position in the file. Because of the different | |
| 38 | * interfaces used by the db(3) package, curses, and users, the line number is | |
| 39 | * 1 based, while the column number is 0 based. Additionally, it is known that | |
| 40 | * the out-of-band line number is less than any legal line number. The line | |
| 41 | * number is of type recno_t, as that's the underlying type of the database. | |
| 42 | * The column number is of type size_t, guaranteeing that we can malloc a line. | |
