GNU Info (elisp)Predicates on MarkersPredicates on Markers ===================== You can test an object to see whether it is a marker, or whether it is either an integer or a marker. The latter test is useful in connection with the arithmetic functions that work with both markers and integers. - Function: markerp object This function returns `t' if OBJECT is a marker, `nil' otherwise. Note that integers are not markers, even though many functions will accept either a marker or an integer. - Function: integer-or-marker-p object This function returns `t' if OBJECT is an integer or a marker, `nil' otherwise. - Function: number-or-marker-p object This function returns `t' if OBJECT is a number (either integer or floating point) or a marker, `nil' otherwise. automatically generated by info2www version 1.2.2.9 |
