.SH DESCRIPTION
|
|
|
|
|
The \fBbaudrate\fR routine returns the output speed of the terminal. The
|
|
|
|
|
number returned is in bits per second, for example \fB9600\fR, and is an
|
|
|
|
|
integer.
|
|
|
|
|
|
|
|
|
|
The \fBerasechar\fR routine returns the user's current erase character.
|
|
|
|
|
|
|
|
|
|
The \fBhas_ic\fR routine is true if the terminal has insert- and delete-
|
|
|
|
|
character capabilities.
|
|
|
|
|
|
|
|
|
|
The \fBhas_il\fR 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 \fBscrollok\fR.
|
|
|
|
|
|
|
|
|
|
The \fBkillchar\fR routine returns the user's current line kill character.
|
|
|
|
|
|
|
|
|
|
The \fBlongname\fR 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 \fBinitscr\fR or \fBnewterm\fR. The area is
|
|
|
|
|
overwritten by each call to \fBnewterm\fR and is not restored by
|
|
|
|
|
\fBset_term\fR, so the value should be saved between calls to
|
|
|
|
|
\fBnewterm\fR if \fBlongname\fR 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, \fBncurses\fR may substitute a
|
|
|
|
|
different video attribute for it. The \fBtermattrs\fR function
|
|
|
|
|
returns a logical \fBOR\fR of all video attributes supported by the
|
|
|
|
|
terminal. This information is useful when a \fBncurses\fR program
|
|
|
|
|
needs complete control over the appearance of the screen.
|
|
|
|
|
|
|
|
|
|
The \fBtermname\fR routine returns the value of the environmental
|
|
|
|
|
variable \fBTERM\fR (truncated to 14 characters).
|
|
|
|
|
.SH RETURN VALUE
|
|
|
|
|
\fBlongname\fR and \fBtermname\fR return \fBNULL\fR on error.
|
|
|
|
|
|
|
|
|
|
Routines that return an integer return \fBERR\fR upon failure and an integer
|
|
|
|
|
value other than \fBERR\fR upon successful completion.
|
|
|
|
|
.SH NOTES
|
|
|
|
|
Note that \fBtermattrs\fR may be a macro.
