a #VteSelectionFunc callback
user data to be passed to the callback
location for storing text attributes
a newly allocated text string, or %NULL.
Extracts a view of the visible part of the terminal. If @is_selected is not %NULL, characters will only be read if @is_selected returns %TRUE after being passed the column and row, respectively. A #VteCharAttributes structure is added to @attributes for each byte added to the returned string detailing the character's position, colors, and other characteristics. The entire scrollback buffer is scanned, so it is possible to read the entire contents of the buffer using this function.
