CURS_TERMATTRS(3CURSES) Curses Library Functions CURS_TERMATTRS(3CURSES)

NAME

curs_termattrs, baudrate, erasechar, has_ic, has_il, killchar,
longname, termattrs, termname - curses environment query routines

SYNOPSIS

cc [ flag ... ] file ... -lcurses [ library ... ]
#include <curses.h>

int baudrate(void);


char erasechar(void);


int has_ic(void);


int has_il(void);


char killchar(void);


char *longname(void);


chtype termattrs(void);


char *termname(void);

DESCRIPTION

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.


With the erasechar() routine, the user's current erase character is
returned.


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().


With the killchar() routine, the user's current line kill character
is returned.


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 doesn't support a video attribute that an
application program is trying to use, curses may substitute a
different video attribute for it. The termattrs() function returns a
logical OR of all video attributes supported by the terminal. This
information is useful when a curses program needs complete control
over the appearance of the screen.


The termname() routine returns the value of the environment variable
TERM (truncated to 14 characters).

RETURN VALUES

longname() and termname() return NULL on error.


Routines that return an integer return ERR upon failure and an
integer value other than ERR upon successful completion.
