+<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 <curses.h>.
+
+ 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="set_term.3x.html">set_term(3x)</A></STRONG>
+ and <STRONG><A HREF="delscreen.3x.html">delscreen(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.1.html">tic(1)</A></STRONG> and <STRONG><A HREF="infocmp.1.html">infocmp(1)</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>.
+
+
+</PRE>
+<H2>NOTES</H2><PRE>
+ The low-level terminfo interface is initialized using <STRONG>se-</STRONG>
+ <STRONG><A HREF="setupterm.3x.html">tupterm(3x)</A></STRONG>. The upper-level curses interface uses the
+ low-level terminfo interface, internally.
+
+
+</PRE>
+<H2>PORTABILITY</H2><PRE>
+ X/Open Curses does not describe any of these except for
+ <STRONG>cur_term</STRONG>. (The inclusion of <STRONG>cur_term</STRONG> appears to be an
+ oversight, since other comparable low-level information is
+ omitted by X/Open).
+
+ Other implementations may have comparable variables. Some
+ implementations provide the variables in their libraries,
+ but omit them from the header files.
