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