.Sh DESCRIPTION
|
|
These functions manipulate curses terminal settings.
|
|
.Pp
|
|
The
|
|
.Fn beep
|
|
function rings the terminal bell, if this is possible.
|
|
Failing that, the terminal screen will be flashed.
|
|
If neither of these are possible, then no action will be taken.
|
|
.Fn flash
|
|
will flash the terminal screen if possible.
|
|
Failing that, the terminal bell will be rung.
|
|
If neither of these are possible then no action will be taken.
|
|
.Pp
|
|
The cursor
|
|
visibility can be set by calling
|
|
.Fn curs_set .
|
|
The following visibility settings are valid for
|
|
.Fn curs_set :
|
|
.Pp
|
|
.Bl -tag -width visibility -compact -offset indent
|
|
.It Visibility
|
|
Effect
|
|
.It 0
|
|
cursor is invisible.
|
|
.It 1
|
|
cursor is normal visibility
|
|
.It 2
|
|
cursor is high visibility
|
|
.El
|
|
.Pp
|
|
A successful call to
|
|
.Fn curs_set
|
|
will return the previous visibility setting for the cursor.
|
|
.Pp
|
|
The
|
|
.Fn delay_output
|
|
function pauses the output to the terminal by sending the appropriate
|
|
number of terminal pad characters such that the transmission time of
|
|
the pad characters will take
|
|
.Fa ms
|
|
milliseconds.
|
|
.Pp
|
|
Calling
|
|
.Fn def_prog_mode
|
|
will cause the current terminal curses setting to be saved.
|
|
A subsequent call to
|
|
.Fn reset_prog_mode ,
|
|
will restore the saved settings.
|
|
This is useful when calls to external programs are made that may
|
|
reset the terminal characteristics.
|
|
.Pp
|
|
The
|
|
.Fn def_shell_mode
|
|
function saves the current terminal line settings.
|
|
These settings are the ones that will be restored when the curses
|
|
application exits.
|
|
Conversely,
|
|
.Fn reset_shell_mode
|
|
will save the current terminal curses settings for later restoration and
|
|
restores the previously saved terminal line settings.
|
|
.Pp
|
|
The
|
|
.Fn echo
|
|
function turns on curses echo mode, characters entered will be echoed
|
|
to the terminal by curses.
|
|
The
|
|
.Fn noecho
|
|
function disables this feature.
|
|
.Pp
|
|
The current erase character for the terminal can be determined by
|
|
calling the
|
|
.Fn erasechar
|
|
function.
|
|
.Pp
|
|
The
|
|
.Fn flushinp
|
|
function discards any pending input for the current screen.
|
|
.Pp
|
|
The modes
|
|
for the current terminal can be reset by calling
|
|
.Fn gettmode ,
|
|
this will perform the initialisation on the terminal that is normally
|
|
done by curses at start up.
|
|
.Pp
|
|
The
|
|
.Fn has_ic
|
|
function returns either
|
|
.Dv TRUE
|
|
or
|
|
.Dv FALSE
|
|
depending on whether or not the terminal has a insert character
|
|
capability or not.
|
|
Similarly the
|
|
.Fn has_il
|
|
function does the same test but for a insert line capability.
|
|
.Pp
|
|
The use of the insert character capability in curses operations can be
|
|
enabled or disabled by calling
|
|
.Fn idcok
|
|
on the desired window.
|
|
Similarly, the use of the insert line capability can be controlled using the
|
|
.Fn idlok
|
|
function.
|
|
.Pp
|
|
The
|
|
.Fn intrflush
|
|
function controls whether or not a flush of the input buffer is
|
|
performed when an interrupt key (kill, suspend or quit) is pressed.
|
|
The
|
|
.Fa win
|
|
parameter is ignored.
|
|
The
|
|
.Fn noqiflush
|
|
function is equivalent to
|
|
.Fn intrflush stdscr FALSE .
|
|
The
|
|
.Fn qiflush
|
|
function is equivalent to
|
|
.Fn intrflush stdscr TRUE .
|
|
.Pp
|
|
The character that performs the line kill function can be determined
|
|
by calling the
|
|
.Fn killchar
|
|
function.
|
|
.Pp
|
|
The
|
|
.Fn meta
|
|
function turns on and off the generation of 8 bit characters by the
|
|
terminal, if
|
|
.Fa flag
|
|
is
|
|
.Dv FALSE
|
|
then only 7 bit characters will be returned, if
|
|
.Fa flag
|
|
is
|
|
.Dv TRUE
|
|
then 8 bit characters will be returned by the terminal.
|
|
.Pp
|
|
The
|
|
.Fn napms
|
|
causes the application to sleep for the number of milliseconds
|
|
specified by
|
|
.Fa ms .
|
|
.Pp
|
|
Calling
|
|
.Fn nl
|
|
will cause curses to map all carriage returns to newlines on input,
|
|
this functionality is enabled by default.
|
|
The
|
|
.Fn nonl
|
|
function disables this behaviour.
|
|
.Pp
|
|
The
|
|
.Fn cbreak
|
|
function will put the terminal into cbreak mode, which means that
|
|
characters will be returned one at a time instead of waiting for a
|
|
newline character, line discipline processing will be performed.
|
|
The
|
|
.Fn nocbreak
|
|
function disables this mode.
|
|
.Pp
|
|
Calling
|
|
.Fn halfdelay
|
|
puts the terminal into the same mode as
|
|
.Fn cbreak
|
|
with the exception that if no character is received within the specified
|
|
number of tenths of a second then the input routine will return
|
|
.Er ERR .
|
|
This mode can be cancelled by calling
|
|
.Fn nocbreak .
|
|
The valid range for the timeout is from 1 to 255 tenths of a second.
|
|
.Pp
|
|
The
|
|
.Fn noraw
|
|
function sets the input mode for the current terminal into Cooked mode,
|
|
that is input character translation and signal character processing is
|
|
performed.
|
|
The
|
|
.Fn raw
|
|
function puts the terminal into Raw mode, no input character
|
|
translation is done nor is signal character processing.
|
|
.Pp
|
|
The terminal
|
|
tty flags can be saved by calling
|
|
.Fn savetty
|
|
and may be restored by calling
|
|
.Fn resetty ,
|
|
the use of these functions is discouraged as they may cause the
|
|
terminal to be put into a state that is incompatible with curses
|
|
operation.
|
|
.Sh RETURN VALUES
|
|
Functions returning pointers will return
|
|
.Dv NULL
|
|
if an error is detected.
|
|
The functions that return an int will return one of the following
|
|
values:
|
|
.Pp
|
|
.Bl -tag -width ERR -compact
|
|
.It Er OK
|
|
The function completed successfully.
|
|
.It Er ERR
|
|
An error occurred in the function.

.Sh NOTES
|
|
The
|
|
.Fn idcok
|
|
and
|
|
.Fn idlok
|
|
currently have no effect on the curses code at all, currently curses
|
|
will always use the terminal insert character and insert line
|
|
capabilities if available.
|
|
.Sh STANDARDS
|
|
The
|
|
.Nx
|
|
Curses library complies with the X/Open Curses specification, part of the
|
|
Single Unix Specification.
|
|
.Sh HISTORY
|
|
The Curses package appeared in
|
|
.Bx 4.0 .
