[nondet]csv_read_file_row(+File, -Row, +Options)
True when Row is a row in File. First unifies Row with the first row in File. Backtracking yields the second, ... row. This interface is an alternative to csv_read_file/3 that avoids loading all rows in memory. Note that this interface does not guarantee that all rows in File have the same arity.

In addition to the options of csv_read_file/3, this predicate processes the option:

line(-Line)
Line is unified with the 1-based line-number from which Row is read.
