There is only one physical cursor per display. To change the position of the physical cursor, you must do a refresh. The window that fills the entire display. A pointer to a C data structure and the graphic representation of that data structure on the display. A window can be thought of as a two-dimensional array representing how all or part of the display looks at any point in time.
Windows range in size from the entire display to a single character.
A single curses subroutine can have two or more versions. Curses subroutines with multiple versions follow distinct naming conventions that identify the separate versions. These conventions add a prefix to a standard curses subroutine and identify what arguments the subroutine requires or what actions take place when the subroutine is called. Identifies a subroutine that first performs a move to the program-supplied coordinates. Some curses subroutines with multiple versions do not include one of the preceding prefixes.
