charpos

Arguments: &optional output-stream

For a Gray stream, charpos calls stream-line-column.

Otherwise:

The output line-character-position may be tracked on a per-character basis, or it may be calculated when needed. If for any reason the charpos cannot be determined it is deemed to be nil.

If the stream tracks charpos, the current value is returned as the result of this function. Otherwise, the calculation is performed and the result returned.

See Details of stream-line-column and charpos in streams.htm. See streams.htm for information on the simple-streams implementation in Allegro CL. The older but still supported Gray streams implementation is described in gray-streams.htm.
