## NAME

           baudrate,  erasechar,  erasewchar, has_ic, has_il, killchar, killwchar,
           longname, term_attrs,  termattrs,  termname  -  get  and  set  terminal
           attributes with curses

## SYNOPSIS

           #include <curses.h>

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

## DESCRIPTION

### baudrate

           baudrate  returns  the  line  speed  of  the terminal, an integer value
           measured in bits per second, for example 9600.

### erasechar, erasewchar

           erasechar returns the terminal's erase character.

           erasewchar stores the erase character in the location referenced by wc.
           If no erase character has been  defined,  it  fails  and  the  location
           referenced by wc is not changed.

### has_ic, has_il

           has_ic  returns  TRUE  if the terminal has insert- and delete-character
           capabilities.

           has_il returns  TRUE  if  the  terminal  has  insert-  and  delete-line
           capabilities,  or  can simulate them using scrolling regions.  It might
           be  used  to  determine  whether  it  would  be  appropriate   to   use
           scrollok(3x) to turn on scrolling.

### killchar, killwchar

           killchar returns the terminal's line kill character.

           killwchar  stores the line-kill character in the location referenced by
           wc.  If no line-kill character has  been  defined,  it  fails  and  the
           location referenced by wc is not changed.

### longname

           longname  returns  a  pointer  to  static  storage containing a verbose
           description of the terminal  being  managed  by  curses.   The  maximum
           length  of  a  verbose  description  is 128 characters.  The storage is
           populated only  after  initscr(3x)  or  newterm(3x)  is  called.   This
           storage  is  overwritten  by  each  call to newterm and not restored by
           set_term(3x), so its contents should be saved between calls to  initscr
           or newterm if longname is 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.  termattrs and term_attrs 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

           termname returns the terminal name used by setupterm(3x).

## RETURN VALUE

           longname and termname return NULL on error.

           Functions that return an integer return ERR upon failure  and  OK  upon
           success.

## NOTES

           erasewchar,  killwchar,  and  term_attrs  are  part  of ncurses's wide-
           character  API,  and  are  not  available  in  its   non-wide-character
           configuration.

           termattrs may be implemented as a macro.

## PORTABILITY

           X/Open Curses Issue 4 describes these functions.

           SVr4  describes  a  successful  return  value only as "an integer value
           other than ERR".

           Most versions of curses truncate the string returned by termname to  14
           characters.

## HISTORY

           4BSD (1980) introduced longname.

           SVr2 (1984) added baudrate, erasechar, killchar, has_ic, and has_il.

           SVr3  (1987)  supplied  termname.   Later  that  year,  SVr3.1  brought
           termattrs.

           X/Open Curses  Issue 4  (1995)  specified  erasewchar,  killwchar,  and
           term_attrs.
