-<H2>DESCRIPTION</H2><PRE>
- This page summarizes variables provided by the <STRONG>curses</STRONG> li-
- brary. A more complete description is given in the <STRONG>curs-</STRONG>
- <STRONG><A HREF="ncurses.3x.html">es(3x)</A></STRONG> manual page.
-
- Depending on the configuration, these may be actual vari-
- ables, or macros (see <STRONG><A HREF="curs_threads.3x.html">curs_threads(3x)</A></STRONG>) which provide
- read-only access to <EM>curses</EM>'s state. In either case, ap-
- plications should treat them as read-only to avoid confus-
- ing the library.
-
- <STRONG>COLOR_PAIRS</STRONG>
- After initializing curses, this variable contains the num-
- ber of color pairs which the terminal can support. Usual-
- ly the number of color pairs will be the product <STRONG>COL-</STRONG>
- <STRONG>ORS</STRONG>*<STRONG>COLORS</STRONG>, however this is not always true:
-
- <STRONG>o</STRONG> a few terminals use HLS colors, which do not follow
- this rule
-
- <STRONG>o</STRONG> terminals supporting a large number of colors are lim-
- ited by the number of color pairs that can be repre-
- sented in a <EM>signed</EM> <EM>short</EM> value.
-
- <STRONG>COLORS</STRONG>
- After initializing curses, this variable contains the num-
- ber of colors which the terminal can support.
-
- <STRONG>COLS</STRONG>
- After initializing curses, this variable contains the
- width of the screen, i.e., the number of columns.
-
- <STRONG>ESCDELAY</STRONG>
- This variable holds the number of milliseconds to wait af-
- ter reading an escape character, to distinguish between an
- individual escape character entered on the keyboard from
- escape sequences sent by cursor- and function-keys (see
- <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG>.
-
- <STRONG>LINES</STRONG>
- After initializing curses, this variable contains the
- height of the screen, i.e., the number of lines.
-
- <STRONG>TABSIZE</STRONG>
- This variable holds the number of columns used by the
- <EM>curses</EM> library when converting a tab character to spaces
- as it adds the tab to a window (see <STRONG><A HREF="curs_addch.3x.html">curs_addch(3x)</A></STRONG>.
-
- <STRONG>The</STRONG> <STRONG>Current</STRONG> <STRONG>Screen</STRONG>
- This implementation of curses uses a special window <STRONG>curscr</STRONG>
- to record its updates to the terminal screen.
-
- <STRONG>The</STRONG> <STRONG>New</STRONG> <STRONG>Screen</STRONG>
- This implementation of curses uses a special window <STRONG>newscr</STRONG>
- to hold updates to the terminal screen before applying
- them to <STRONG>curscr</STRONG>.
-
- <STRONG>The</STRONG> <STRONG>Standard</STRONG> <STRONG>Screen</STRONG>
- Upon initializing curses, a default window called <STRONG>stdscr</STRONG>,
- which is the size of the terminal screen, is created.
- Many curses functions use this window.
-
-
-</PRE>
-<H2>NOTES</H2><PRE>
- The curses library is initialized using either
- <STRONG><A HREF="initscr.3x.html">initscr(3x)</A></STRONG>, or <STRONG><A HREF="newterm.3x.html">newterm(3x)</A></STRONG>.
-
- If <STRONG>curses</STRONG> is configured to use separate curses/terminfo
- libraries, most of these variables reside in the curses
- library.
-
-
-</PRE>
-<H2>PORTABILITY</H2><PRE>
- ESCDELAY and TABSIZE are extensions, not provided in most
- other implementations of curses.
