       This page summarizes  variables  provided  by  the  curses  library's  low-level  terminfo
       interface.  A more complete description is given in the curs_terminfo(3X) manual page.

       Depending   on   the  configuration,  these  may  be  actual  variables,  or  macros  (see
       threads(3NCURSES)) which provide read-only access to  curses's  state.   In  either  case,
       applications should treat them as read-only to avoid confusing the library.

   Alternate Character Set Mapping
       After  initializing the curses or terminfo interfaces, the acs_map array holds information
       used  to  translate  cells  with  the  A_ALTCHARSET  video  attribute  into   line-drawing

       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.

   Current Terminal Data
       After  initializing  the  curses  or  terminfo  interfaces,  the  cur_term  contains  data
       describing  the  current  terminal.   This  variable  is  also  set  as  a  side-effect of
       set_term(3X) and delscreen(3X).

       It is possible to save a value of cur_term for subsequent use as a parameter to  set_term,
       for  switching between screens.  Alternatively, one can save the return value from newterm
       or setupterm to reuse in set_term.

   Terminfo Names
       The tic(1) and infocmp(1) 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 "l" (ell) in their names: boolfnames, numfnames,
       and strfnames.

       These are the short names for terminfo capabilities: boolnames, numnames, and strnames.

       These are the corresponding names used for termcap descriptions: boolcodes, numcodes,  and

   Terminal Type
       On initialization of the curses or terminfo interfaces, setupterm copies the terminal name
       to the array ttytype.

   Terminfo Names
       In addition to the variables, <term.h> also defines a symbol for each terminfo  capability
       long name.  These are in terms of the symbol CUR, which is defined

       #define CUR cur_term->type.

       These  symbols  provide  a  faster  method  of  accessing terminfo capabilities than using
       tigetstr(3X), etc.


       The low-level terminfo interface is  initialized  using  setupterm(3X).   The  upper-level
       curses interface uses the low-level terminfo interface, internally.


       X/Open  Curses  does  not  describe  any  of these except for cur_term.  (The inclusion of
       cur_term 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.

       All implementations which provide terminfo interfaces add definitions as described in  the
       Terminfo  Names  section.   Most,  but  not  all,  base  the  definition upon the cur_term


       ncurses(3NCURSES), terminfo(3NCURSES), threads(3NCURSES), terminfo(5).
