## char-from-line-number

Arguments: stream line-number

Returns an integer indicating the character index of the first character of the line-number'th line of text. line-number should be a non-negative integer, with 0 indicating the first line of text. stream can be a `multi-line-editable-text` control, or a `text-edit-pane`.

The character index (the returned value) pertains to the string that is in the control, which may differ from a lisp string that was placed into the control programmatically by calling set-text. In particular, the Windows multi-line text-editing control that is currently used by Common Graphics always contains a carriage return / linefeed pair to separate lines of text, where a lisp string has a single newline character. Text is converted automatically when it is added to or copied from the control.
