Arguments: stream &optional (stream-units-p t)
Returns the value of the left-margin property of the stream argument. The value is in space-widths (the width of the space character in the current font of the argument) unless the optional stream-units-p argument is specified true, in which case pixel units rather than space-widths are used.
When drawing text using Vommon Lisp functions such as print or format, a newline will move the current position to the left margin. On the other hand, when using Common Graphics drawing functions, an application should take note of a stream's margins and position the drawing appropriately.
left-margin is a
property of all Common Graphics streams, though it is most useful with
printer streams, where "hardware margins" makes margin computation
less straightforward. See *default-printer-left-margin* for
details.
