+ After initializing the curses or terminfo interfaces, the <STRONG>cur_term</STRONG>

+ set as a side-effect of <STRONG><A HREF="curs_initscr.3x.html">set_term(3x)</A></STRONG> and <STRONG><A HREF="curs_initscr.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><A HREF="curs_terminfo.3x.html">setupterm(3x)</A></STRONG> to reuse in
+ <STRONG>set_term</STRONG>.

+ The <STRONG><A HREF="tic.1m.html">tic(1)</A></STRONG> and <STRONG><A HREF="infocmp.1m.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, although the hash-tables used by the terminfo and termcap
+ functions are not available.
+
+ The long terminfo capability names use a "f" (eff) in their names:
+ <STRONG>boolfnames</STRONG>, <STRONG>numfnames</STRONG>, and <STRONG>strfnames</STRONG>.
+
+ These are the short names for terminfo capabilities: <STRONG>boolnames</STRONG>,
+ <STRONG>numnames</STRONG>, and <STRONG>strnames</STRONG>.
+
+ These are the corresponding names used for termcap descriptions:
+ <STRONG>boolcodes</STRONG>, <STRONG>numcodes</STRONG>, and <STRONG>strcodes</STRONG>.
+
+
+</PRE><H3><a name="h3-Terminal-Type">Terminal Type</a></H3><PRE>
+ A terminal description begins with one or more terminal names separated
+ by "|" (vertical bars). On initialization of the curses or terminfo
+ interfaces, <STRONG><A HREF="curs_terminfo.3x.html">setupterm(3x)</A></STRONG> copies the terminal names to the array
+ <STRONG>ttytype</STRONG>.
+
+
+</PRE><H3><a name="h3-terminfo-Names"><EM>terminfo</EM> Names</a></H3><PRE>
+ In addition to the variables, <STRONG><term.h></STRONG> also defines a symbol for each
+ terminfo capability <EM>long</EM> <EM>name</EM>. These are in terms of the symbol <STRONG>CUR</STRONG>,
+ which is defined
+
+ #define CUR ((TERMTYPE *)(cur_term))->
+
+ These symbols provide a faster method of accessing terminfo
+ capabilities than using <STRONG><A HREF="curs_terminfo.3x.html">tigetstr(3x)</A></STRONG>, etc.
+
+ The actual definition of <STRONG>CUR</STRONG> depends upon the implementation, but each
+ terminfo library provides these long names defined to point into the
+ current terminal description loaded into memory.

+ X/Open Curses does not describe any of these except for <STRONG>cur_term</STRONG>. (The

+ 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.

+ All implementations which provide terminfo interfaces add definitions
