curs_termattrs(3) curs_termattrs(3)
NAME
baudrate, erasechar, has_ic, has_il, killchar, longname,
termattrs, termname - curses environment query routines
SYNOPSIS
#include <curses.h>
int baudrate(void);
char erasechar(void);
int has_ic(void);
int has_il(void);
char killchar(void);
char *longname(void);
attr_t 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 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 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
function returns a logical OR of all video attributes sup-
ported 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
1
curs_termattrs(3) curs_termattrs(3)
environmental variable TERM (truncated to 14 characters).
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.
