Next: Changing Markers, Previous: Creating Markers, Up: Markers [Contents][Index]
This section describes the functions for accessing the components of a marker object.
This function returns the position that marker points to, or
nil
if it points nowhere.
This function returns the buffer that marker points into, or
nil
if it points nowhere.
(setq m (make-marker)) ⇒ #<marker in no buffer>
(marker-position m) ⇒ nil
(marker-buffer m) ⇒ nil
(set-marker m 3770 (current-buffer)) ⇒ #<marker at 3770 in markers.texi>
(marker-buffer m) ⇒ #<buffer markers.texi>
(marker-position m) ⇒ 3770
Two distinct markers are considered equal
(even though not
eq
) to each other if they have the same position and buffer, or
if they both point nowhere.
