![]() On input, curses is also able to translateĪrrow and function keys that transmit escape sequences into single val. Modes as underlined, in reverse video, or in color on terminals that In addition to drawing characters on the screen, video attributes andĬolors may be supported, causing the characters to show up in such Which are not constrained to the size of the screen and whose contents Special windows called pads may also be manipulated. TheĬharacters in a window are actually of type chtype, (character andĪttribute data) so that other information about the character may also Telling curses to make the user's CRT screen look like stdscr. The routines not beginning with w affect stdscr.Īfter using routines to manipulate a window, refresh(3X) is called, With names beginning with w, allowing the user to specify a window. More general versions of these routines are included Structures are manipulated with routines described here and elsewhere Windows are referred to by variables declared as WINDOW *. Ing the two will result in unpredictable, and undesired, effects. ![]() This means that you can either use stdscr orĭivide the screen into tiled windows and not using stdscr at all. Note that curses does not handle overlapping windows, that's done by Stdscr, which is the size of the terminal screen, is supplied. Ters representing all or part of a CRT screen.

Differencesįrom the SVr4 curses are summarized under the EXTENSIONS and PORTABIL- ITY sections below and described in detail in the respective EXTEN- SIONS, PORTABILITY and BUGS sections of individual man pages. Ncurses library is freely redistributable in source form. XSI stands for X/Open System Interfaces Extension. UNIX, and XPG4 (X/Open Portability Guide) curses (also known as XSIĬurses). The ncurses library emulates the curses library of System V Release 4 This describes ncurses version 6.0 (patch 20170422). Replacement for 4.4BSD classic curses, which has been discontinued. This implementation is "new curses" (ncurses) and is the approved Method of updating character screens with reasonable optimization.
