    DESCRIPTION

           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  curs-
           es's state.  In either case, applications should treat them as read-on-
           ly 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 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  vari-
           able.
    
       Current Terminal Data
           After initializing the curses or terminfo interfaces, the cur_term con-
           tains 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 pa-
           rameter 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
       Terminal Type
           On initialization of  the  curses  or  terminfo  interfaces,  setupterm
           copies the terminal name to the array ttytype.
    
    
    

    NOTES

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

    PORTABILITY

           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  compara-
           ble low-level information is omitted by X/Open).
    
           Other  implementations may have comparable variables.  Some implementa-
           tions provide the variables in their libraries, but omit them from  the
           header files.
