-<H2>DESCRIPTION</H2><PRE>
- This page summarizes variables provided by the <STRONG>curses</STRONG> li-
- brary's low-level terminfo interface. A more complete de-
- scription is given in the <STRONG><A HREF="curs_terminfo.3x.html">curs_terminfo(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>Alternate</STRONG> <STRONG>Character</STRONG> <STRONG>Set</STRONG> <STRONG>Mapping</STRONG>
- After initializing the curses or terminfo interfaces, the
- <STRONG>acs_map</STRONG> array holds information used to translate cells
- with the <STRONG>A_ALTCHARSET</STRONG> video attribute into line-drawing
- characters.
-
- The encoding of the information in this array has changed
- periodically. Application developers need only know that
- it is used for the "ACS_" constants in &lt;curses.h&gt;.
-
- The comparable data for the wide-character library is a
- private variable.
-
- <STRONG>Current</STRONG> <STRONG>Terminal</STRONG> <STRONG>Data</STRONG>
- After initializing the curses or terminfo interfaces, the
- <STRONG>cur_term</STRONG> contains data describing the current terminal.
- This variable is also set as a side-effect of <STRONG><A HREF="curs_initscr.3x.html">curs_initscr(3x)</A></STRONG>
- and <STRONG><A HREF="curs_initscr.3x.html">curs_initscr(3x)</A></STRONG>.
-
- It is possible to save a value of <STRONG>cur_term</STRONG> for subsequent
- use as a parameter to <STRONG>set_term</STRONG>, for switching between
- screens. Alternatively, one can save the return value
- from <STRONG>newterm</STRONG> or <STRONG>setupterm</STRONG> to reuse in <STRONG>set_term</STRONG>.
-
- <STRONG>Terminfo</STRONG> <STRONG>Names</STRONG>
- The <STRONG><A HREF="tic.1m.html">tic(1m)</A></STRONG> and <STRONG><A HREF="infocmp.1m.html">infocmp(1m)</A></STRONG> programs use lookup tables for
- the long and short names of terminfo capabilities, as well
- as the corresponding names for termcap capabilities.
- These are available to other applications, though the
- hash-tables are not available.
-
- The long terminfo capability names use a "l" (ell) in
- their names: boolfnames numfnames strfnames
-
- These are the short names for terminfo capabilities: bool-
- names, numnames, and strnames.
-
- These are the corresponding names used for termcap de-
- scriptions: boolcodes, numcodes, and strcodes.
-
- <STRONG>Terminal</STRONG> <STRONG>Type</STRONG>
- On initialization of the curses or terminfo interfaces,
- <STRONG>setupterm</STRONG> copies the terminal name to the array <STRONG>ttytype</STRONG>.
