A List function that deletes items from a list based on an array of positions
#include <Xm/List.h> void XmListDeletePositions Widget widgetint *position_listint position_count
XmListDeletePositions deletes noncontiguous items from a list. The function deletes all items whose corresponding positions appear in the position_list array. A warning message is displayed if a specified position is invalid; that is, the value is 0, a negative integer, or a number greater than the number of items in the list.
