curses
curses is the name of various program libraries for displaying character-oriented user interfaces (Text User Interface, TUI) regardless of the displaying text terminal or terminal emulator .
First there was an implementation of the Berkeley Software Distribution (BSD) 4.4, which was followed by a further development for Release 4 of System V in 1989 . In the early 1990s, the GNU project developed a free implementation called ncurses based on this model , which is predominantly in use today. Other further developments are the Public Domain Curses (PDCurses) started in 1987 by Mark Hessling and pcurses (1982) by Pavel Curtis. There is a standard from X / Open that is extremely close to the System V implementation.
Sample program
Simple hello world program with curses:
#include <curses.h>
int main(void)
{
initscr();
printw("Hallo Welt!");
refresh();
getch();
endwin();
return 0;
}
