NAME

   baudrate,  erasechar,  erasewchar, has_ic, has_il, killchar, killwchar,
   longname, term_attrs, termattrs, termname -  curses  environment  query
   routines

SYNOPSIS

   #include <curses.h>

   int baudrate(void);
   char erasechar(void);
   int erasewchar(wchar_t *ch);
   bool has_ic(void);
   bool has_il(void);
   char killchar(void);
   int killwchar(wchar_t *ch);
   char *longname(void);
   attr_t term_attrs(void);
   chtype termattrs(void);
   char *termname(void);

DESCRIPTION

   baudrate
   The  baudrate  routine  returns  the output speed of the terminal.  The
   number returned is in bits per second, for  example  9600,  and  is  an
   integer.

   erasechar, erasewchar
   The erasechar routine returns the user's current erase character.

   The  erasewchar  routine  stores  the  current  erase  character in the
   location referenced by ch.  If no erase character has been defined, the
   routine fails and the location referenced by ch is not changed.

   has_is, has_il
   The  has_ic  routine  is  true  if the terminal has insert- and delete-
   character capabilities.

   The has_il routine is true if the terminal has insert- and  delete-line
   capabilities, or can simulate them using scrolling regions.  This might
   be used to determine if it would be appropriate  to  turn  on  physical
   scrolling using scrollok.

   killchar, killwchar
   The killchar routine returns the user's current line kill character.

   The  killwchar  routine  stores  the current line-kill character in the
   location referenced by ch.  If no line-kill character has been defined,
   the routine fails and the location referenced by ch is not changed.

   longname
   The  longname  routine  returns a pointer to a static area containing a
   verbose description of the current terminal.  The maximum length  of  a
   verbose  description  is  128 characters.  It is defined only after the
   call to initscr or newterm.  The area is overwritten by  each  call  to
   newterm  and  is not restored by set_term, so the value should be saved
   between calls to newterm if longname is going to be used with  multiple
   terminals.

   termattrs, term_attrs
   If  a  given  terminal  does  not  support  a  video  attribute that an
   application program is trying to use, curses may substitute a different
   video  attribute for it.  The termattrs and term_attrs functions return
   a logical OR of all video attributes supported by the terminal using A_
   and  WA_  constants  respectively.   This  information is useful when a
   curses program needs  complete  control  over  the  appearance  of  the
   screen.

   termname
   The termname routine returns the terminal name used by setupterm.

RETURN VALUE

   longname and termname return NULL on error.

   Routines  that  return  an integer return ERR upon failure and OK (SVr4
   only specifies "an integer  value  other  than  ERR")  upon  successful
   completion.

NOTES

   Note that termattrs may be a macro.

PORTABILITY

   The XSI Curses standard, Issue 4 describes these functions.  It changes
   the return type of termattrs to the new type attr_t.  Most versions  of
   curses truncate the result returned by termname to 14 characters.
