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

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

       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  ref-
       erenced by ch is not changed.

       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.

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

       The killwchar routine stores the current line-kill charac-
       ter 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.

       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 charac-
       ters.   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.

       If a given terminal doesn't support a video attribute that
       an application program is trying to use, curses  may  sub-
       stitute 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_ con-
       stants respectively.  This information is  useful  when  a
       curses  program needs complete control over the appearance
       of the screen.

       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 func-
       tions.  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.
