LXV. Ncurses terminal screen control functions

Ostrze¿enie

Ten moduł jest w stadium EKSPERYMENTALNYM. Oznacza to, że zachowanie tych funkcji, ich nazwy, w zasadzie wszystko udokumentowane tutaj może zostać zmienione w przyszłych wersjach PHP bez wcześniejszego uprzedzenia. Używaj tego modułu na własne ryzyko.

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.
