NAME

       SP, acs_map, boolcodes, boolfnames, boolnames, cur_term, numcodes, numfnames, numnames, strcodes, strfnames, strnames, ttytype - curses
       terminfo global variables

SYNOPSIS

       #include <curses.h>
       #include <term.h>

       chtype acs_map[];
       NCURSES_CONST char * const * boolcodes;
       NCURSES_CONST char * const * boolfnames;
       NCURSES_CONST char * const * boolnames;
       TERMINAL * cur_term;
       NCURSES_CONST char * const * numcodes;
       NCURSES_CONST char * const * numfnames;
       NCURSES_CONST char * const * numnames;
       NCURSES_CONST char * const * strcodes;
       NCURSES_CONST char * const * strfnames;
       NCURSES_CONST char * const * strnames;
       char ttytype[];

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 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 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.

   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, 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: boolnames, numnames, and strnames.

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

   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 inter-
       face, 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  com-
       parable 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.
