SYNOPSIS

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 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.

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 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.

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.

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.

The termname routine returns the terminal name used by setupterm.  

RETURN VALUE

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