High Quality Content by WIKIPEDIA articles! PDCurses is a public domain curses programming library for DOS, Windows, X11 and SDL. While development of the original curses library halted in the mid-1990s, the development of ncurses and PDcurses continued. PDcurses implements most of the functions available in the original X/Open and System V R4 curses. Development started in 1987 to support the editor THE. It supports many compilers for these platforms. The X11 port lets you recompile existing text-mode curses programs to produce native X11 applications.
