curs_termattrs(3X)curs_termattrs(3X)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 terminal. 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 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 applica‐
tion 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 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 com‐
pletion.
NOTES
Note that termattrs may be a macro.
PORTABILITY
The XSI Curses standard, Issue 4 describes these functions. It changes
the return type of termattrs to the new type attr_t.
