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. Note that Line is not the physical line, but rather the
logical record number.
- To be done
- - Input is read line by line. If a record separator is
embedded in a quoted field, parsing the record fails and
another line is added to the input. This does not nicely
deal with other reasons why parsing the row may fail.
