Ncurses terminal screen control functions


LXV. Ncurses terminal screen control functions

Avertissement

Ce module est EXPERIMENTAL. Cela signifie que le comportement de ces fonctions, leurs noms et concrètement, TOUT ce qui est documenté ici peut changer dans un futur proche, SANS PREAVIS! Soyez-en conscient, et utiliser ce module à vos risques et périls.

What is ncurses?

ncurses (new curses) is a free software emulation of curses in System V Rel 4.0 (and above). It uses terminfo format, supports pads, colors, multiple highlights, form characters and function key mapping.

Platforms

Ncurses is available for the following platforms:

  • AIX

  • BeOS

  • Cygwin

  • Digital Unix (aka OSF1)

  • FreeBSD

  • GNU/Linux

  • HPUX

  • IRIX

  • OS/2

  • SCO OpenServer

  • Solaris

  • SunOS

Requirements

You need the ncurses libraries and headerfiles. Download the latest version from the ftp://ftp.gnu.org/pub/gnu/ncurses/ or from an other GNU-Mirror.

Installation

To get these functions to work, you have to compile the CGI version of PHP with --with-ncurses.

Ncurses predifined constants

Error codes

On error ncurses functions return NCURSES_ERR.
