Ignore values #11

Closed michael-customlbs closed 8 years ago

michael-customlbs commented 8 years ago

Sometimes I don't want to read all values. Is there a way to ignore columns e.g.:

int i;
in.read_row(i, io::ignore, io::ignore, io::ignore);

This would save me a lot of lines.

Hi,

just do

char*ignore; ... in.read_row(i, ignore, ignore, ignore);

As this involves no copy it should be fast.

If you want to ignore all values of a column then using io::ignore_extra_column is probably better though.

Best Regards Ben Strasser
