Functions that expect an argument to be a position (an integer), but accept a marker as a substitute, normally ignore which buffer the marker points into; they convert the marker to an integer, and use that integer, exactly as if you had -passed the integer as the argument. Markers used this way usually -point to a position in the buffer that the function will operate on, -but if not, they are converted to integers anyway. @xref{Markers}. +passed the integer as the argument, even if the marker points to the +``wrong'' buffer. A marker that points nowhere cannot convert to an +integer; using it instead of an integer causes an error. +@xref{Markers}. See also the ``field'' feature (@pxref{Fields}), which provides functions that are used by many cursor-motion commands. |
