Terminal Type

+       A  terminal  description  begins with one or more terminal
+       names separated by "|" (vertical bars).  On initialization
+       of the curses or terminfo interfaces, setupterm(3x) copies

+

Terminfo Names

+       In addition to the variables, <term.h> also defines a sym-
+       bol  for each terminfo capability long name.  These are in
+       terms of the symbol CUR, which is defined
+
+       #define CUR ((TERMTYPE *)(cur_term))->
+
+       These symbols provide a faster method of accessing termin-
+       fo capabilities than using tigetstr(3x), etc.
+
+       The  actual definition of CUR depends upon the implementa-
+       tion, but each terminfo library provides these long  names
+       defined  to  point  into  the current terminal description
+       loaded into memory.

NOTES
