.Fd baudrate "" \*m
|
|
.De
|
|
Returns the output baud rate of the terminal.
|
|
This is a system dependent constant
|
|
(defined in
|
|
.b <sys/tty.h>
|
|
on BSD systems,
|
|
which is included by
|
|
.b <curses.h> ).
|
|
.Ds
|
|
.Fd delwin win
|
|
WINDOW *win;
|
|
.De
|
|
Deletes the window from existence.
|
|
All resources are freed for future use by
|
|
.b calloc (3).
|
|
If a window has a
|
|
.Fn subwin
|
|
allocated window inside of it,
|
|
deleting the outer window
|
|
the subwindow is not affected,
|
|
even though this does invalidate it.
|
|
Therefore,
|
|
subwindows should be deleted before their
|
|
outer windows are.
|
|
.Ds
|
|
.Fd endwin
|
|
.De
|
|
Finish up window routines before exit.
|
|
This restores the terminal to the state it was before
|
|
.Fn initscr
|
|
(or
|
|
.Fn gettmode
|
|
and
|
|
.Fn setterm )
|
|
was called.
|
|
It should always be called before exiting.
|
|
It does not exit.
|
|
This is especially useful for resetting tty stats
|
|
when trapping rubouts via
|
|
.b signal (2).
|
|
.Ds
|
|
.Fd erasechar "" \*m
|
|
.De
|
|
Returns the erase character
|
|
for the terminal,
|
|
.i i.e. ,
|
|
the character used by the user to erase a single character from the input.
|
|
.Ds
|
|
.Fd getcap str "" "char *"
|
|
char *str;
|
|
.De
|
|
Return a pointer to the
|
|
.b termcap
|
|
capability described by
|
|
.Vn str
|
|
(see
|
|
.b termcap (5)
|
|
for details).
|
|
.Ds
|
|
.Fd getyx win\*,y\*,x \*m
|
|
WINDOW *win;
|
|
int y\*,x;
|
|
.De
|
|
Puts the current \*y of
|
|
.Vn win
|
|
in the variables
|
|
.Vn y
|
|
and
|
|
.Vn x .
|
|
Since it is a macro,
|
|
not a function,
|
|
you do not pass the address
|
|
of
|
|
.Vn y
|
|
and
|
|
.Vn x .
|
|
.Ds
|
|
.Fd inch "" \*m
|
|
.Fd winch win \*m
|
|
WINDOW *win;
|
|
.De
|
|
Returns the character at the current \*(y
|
|
on the given window.
|
|
This does not make any changes to the window.
|
|
.Ds
|
|
.Fd initscr
|
|
.De
|
|
Initialize the screen routines.
|
|
This must be called before any of the screen routines are used.
|
|
It initializes the terminal-type data and such,
|
|
and without it none of the routines can operate.
|
|
If standard input is not a tty,
|
|
it sets the specifications to the terminal
|
|
whose name is pointed to by
|
|
.Vn Def\*_term
|
|
(initialy "dumb").
|
|
If the boolean
|
|
.Vn My\*_term
|
|
is true,
|
|
.Vn Def\*_term
|
|
is always used.
|
|
If the system supports the
|
|
.b TIOCGWINSZ
|
|
.Fn ioctl "" "" 2
|
|
call,
|
|
it is used to get the number of lines and columns for the terminal,
|
|
otherwise it is taken from the
|
|
.b termcap
|
|
description.
|
|
.Ds
|
|
.Fd killchar "" \*m
|
|
.De
|
|
Returns the line kill character
|
|
for the terminal,
|
|
.i i.e. ,
|
|
the character used by the user to erase an entire line from the input.
|
|
.Ds
|
|
.Fd leaveok win\*,boolf \*m
|
|
WINDOW *win;
|
|
bool boolf;
|
|
.De
|
|
Sets the boolean flag for leaving the cursor after the last change.
|
|
If
|
|
.Vn boolf
|
|
is TRUE,
|
|
the cursor will be left after the last update on the terminal,
|
|
and the current \*y for
|
|
.Vn win
|
|
will be changed accordingly.
|
|
If it is FALSE,
|
|
it will be moved to the current \*y.
|
|
This flag
|
|
(initialy FALSE)
|
|
retains its value until changed by the user.
|

.Ds

.Fd longname termbuf\*,name
|
|
char *termbuf\*,*name;
|
|
.Fd fullname termbuf\*,name
|
|
char *termbuf\*,*name;
|
|
.De
|
|
.Fn longname
|
|
fills in
|
|
.Vn name
|
|
with the long name of the terminal described by the
|
|
.b termcap
|
|
entry in
|
|
.Vn termbuf .
|
|
It is generally of little use,
|
|
but is nice for telling the user in a readable format what terminal
|
|
we think he has.
|
|
This is available in the global variable
|
|
.Vn ttytype .
|
|
.Vn termbuf
|
|
is usually set via the termlib routine
|
|
.Fn tgetent .
|
|
.Fn fullname
|
|
is the same as
|
|
.Fn longname ,
|
|
except that it gives the fullest name given in the entry,
|
|
which can be quite verbose.
|
|
.Ds
|
|
.Fd mvwin win\*,y\*,x
|
|
WINDOW *win;
|
|
int y, x;
|
|
.De
|
|
Move the home position of the window
|
|
.Vn win
|
|
from its current starting coordinates
|
|
to
|
|
.Vn y\*,x ). (
|
|
If that would put part or all of the window
|
|
off the edge of the terminal screen,
|
|
.Fn mvwin
|
|
returns ERR and does not change anything.
|
|
For subwindows,
|
|
.Fn mvwin
|
|
also returns ERR if you attempt to move it off its main window.
|
|
If you move a main window,
|
|
all subwindows are moved along with it.
|
|
.Ds
|
|
.Fd newwin lines\*,cols\*,begin\*_y\*,begin\*_x "" "WINDOW *"
|
|
int lines\*,cols\*,begin\*_y\*,begin\*_x;
|
|
.De
|
|
Create a new window with
|
|
.Vn lines
|
|
lines and
|
|
.Vn cols
|
|
columns starting at position
|
|
.Vn begin\*_y\*,begin\*_x ). (
|
|
If either
|
|
.Vn lines
|
|
or
|
|
.Vn cols
|
|
is 0 (zero),
|
|
that dimension will be set to
|
|
.Vn "LINES \- begin\*_y" ) (
|
|
or
|
|
.Vn "COLS \- begin\*_x" ) (
|
|
respectively.
|
|
Thus, to get a new window of dimensions
|
|
.Vn LINES
|
|
\(mu
|
|
.Vn COLS ,
|
|
use
|
|
.Fn newwin . "" 0\*,0\*,0\*,0
|
|
.Ds
|
|
.Fd nl "" \*m
|
|
.Fd nonl "" \*m
|
|
.De
|
|
Set or unset the terminal to/from nl mode,
|
|
.i i.e. ,
|
|
start/stop the system from mapping
|
|
.b <RETURN>
|
|
to
|
|
.b <LINE-FEED> .
|
|
If the mapping is not done,
|
|
.Fn refresh
|
|
can do more optimization,
|
|
so it is recommended, but not required, to turn it off.
|
|
.Ds
|
|
.Fd scrollok win\*,boolf \*m
|
|
WINDOW *win;
|
|
bool boolf;
|
|
.De
|
|
Set the scroll flag for the given window.
|
|
If
|
|
.Vn boolf
|
|
is FALSE, scrolling is not allowed.
|
|
This is its default setting.
|
|
.Ds
|
|
.Fd touchline win\*,y\*,startx\*,endx
|
|
WINDOW *win;
|
|
int y\*,startx\*,endx;
|
|
.De
|
|
This function performs a function similar to
|
|
.Fn touchwin
|
|
on a single line.
|
|
It marks the first change for the given line
|
|
to be
|
|
.Vn startx ,
|
|
if it is before the current first change mark,
|
|
and
|
|
the last change mark is set to be
|
|
.Vn endx
|
|
if it is currently less than
|
|
.Vn endx .
|
|
.Ds
|
|
.Fd touchoverlap win1\*,win2
|
|
WINDOW *win1, *win2;
|
|
.De
|
|
Touch the window
|
|
.Vn win2
|
|
in the area which overlaps with
|
|
.Vn win1 .
|
|
If they do not overlap,
|
|
no changes are made.
|
|
.Ds
|
|
.Fd touchwin win
|
|
WINDOW *win;
|
|
.De
|
|
Make it appear that the every location on the window
|
|
has been changed.
|
|
This is usually only needed for refreshes with overlapping windows.
|
|
.Ds
|
|
.Fd subwin win\*,lines\*,cols\*,begin\*_y\*,begin\*_x "" "WINDOW *"
|
|
WINDOW *win;
|
|
int lines\*,cols\*,begin\*_y\*,begin\*_x;
|
|
.De
|
|
Create a new window with
|
|
.Vn lines
|
|
lines and
|
|
.Vn cols
|
|
columns starting at position
|
|
.Vn begin\*_y\*,begin\*_x ) (
|
|
inside the window
|
|
.i win .
|
|
This means that any change made to either window
|
|
in the area covered
|
|
by the subwindow will be made on both windows.
|
|
.Vn begin\*_y\*,begin\*_x
|
|
are specified relative to the overall screen,
|
|
not the relative (0\*,0) of
|
|
.Vn win .
|
|
If either
|
|
.Vn lines
|
|
or
|
|
.Vn cols
|
|
is 0 (zero),
|
|
that dimension will be set to
|
|
.Vn "LINES \- begin\*_y" ) (
|
|
or
|
|
.Vn "COLS \- begin\*_x" ) (
|
|
respectively.
|
|
.Ds
|
|
.Fd unctrl ch \*m
|
|
char ch;
|
|
.De
|
|
This is actually a debug function for the library,
|
|
but it is of general usefulness.
|
|
It returns a string which is a representation of
|
|
.Vn ch .
|
|
Control characters become their upper-case equivalents preceded by a "^".
|
|
Other letters stay just as they are.
|
|
To use
|
|
.Fn unctrl ,
|
|
you may have to have
|
|
.b #include\ <unctrl.h>
|
|
in your file.
