+ amend internal use of tputs to consistently use the number of lines affected, e.g., for insert/delete character operations. While merging terminfo source early in 1995, several descriptions used the "*" proportional delay for these operations, prompting a change in doupdate. + regenerate llib-* files. + regenerate HTML manpages. + fix several formatting issues with manual pages.

The <STRONG>getch</STRONG>, <STRONG>wgetch</STRONG>, <STRONG>mvgetch</STRONG> and <STRONG>mvwgetch</STRONG>, routines read a
|
|
character from the window. In no-delay mode, if no input
|
|
is waiting, the value <STRONG>ERR</STRONG> is returned. In delay mode, the
|
|
program waits until the system passes text through to the
|
|
program. Depending on the setting of <STRONG>cbreak</STRONG>, this is af-
|
|
ter one character (cbreak mode), or after the first new-
|
|
line (nocbreak mode). In half-delay mode, the program
|
|
waits until a character is typed or the specified timeout
|
|
has been reached.
|
|
|
|
If <STRONG>echo</STRONG> is enabled, and the window is not a pad, then the
|
|
character will also be echoed into the designated window
|
|
according to the following rules:
|
|
|
|
<STRONG>o</STRONG> If the character is the current erase character, left
|
|
arrow, or backspace, the cursor is moved one space to
|
|
the left and that screen position is erased as if
|
|
<STRONG>delch</STRONG> had been called.
|
|
|
|
<STRONG>o</STRONG> If the character value is any other <STRONG>KEY_</STRONG> define, the
|
|
user is alerted with a <STRONG>beep</STRONG> call.
|
|
|
|
<STRONG>o</STRONG> If the character is a carriage-return, and if <STRONG>nl</STRONG> is
|
|
enabled, it is translated to a line-feed after echo-
|
|
ing.
|
|
|
|
<STRONG>o</STRONG> Otherwise the character is simply output to the
|
|
screen.
|
|
|
|
If the window is not a pad, and it has been moved or modi-
|
|
fied since the last call to <STRONG>wrefresh</STRONG>, <STRONG>wrefresh</STRONG> will be
|
|
called before another character is read.
|

|
|
If <STRONG>keypad</STRONG> is <STRONG>TRUE</STRONG>, and a function key is pressed, the to-
|
|
ken for that function key is returned instead of the raw
|
|
characters:
|
|
|
|
<STRONG>o</STRONG> The predefined function keys are listed in <STRONG><curses.h></STRONG>
|
|
as macros with values outside the range of 8-bit char-
|
|
acters. Their names begin with <STRONG>KEY_</STRONG>.
|
|
|
|
<STRONG>o</STRONG> Other (user-defined) function keys which may be de-
|
|
fined using <STRONG><A HREF="define_key.3x.html">define_key(3x)</A></STRONG> have no names, but also are
|
|
expected to have values outside the range of 8-bit
|
|
characters.
|
|
|
|
Thus, a variable intended to hold the return value of a
|
|
function key must be of short size or larger.
|
|
|
|
When a character that could be the beginning of a function
|
|
key is received (which, on modern terminals, means an es-
|
|
cape character), <STRONG>curses</STRONG> sets a timer. If the remainder of
|
|
the sequence does not come in within the designated time,
|
|
the character is passed through; otherwise, the function
|
|
key value is returned. For this reason, many terminals
|
|
experience a delay between the time a user presses the es-
|
|
cape key and the escape is returned to the program.
|
|
|
|
In <STRONG>ncurses</STRONG>, the timer normally expires after the value in
|
|
<STRONG>ESCDELAY</STRONG> (see <STRONG><A HREF="curs_variables.3x.html">curs_variables(3x)</A></STRONG>). If <STRONG>notimeout</STRONG> is <STRONG>TRUE</STRONG>,
|
|
the timer does not expire; it is an infinite (or very
|
|
large) value. Because function keys usually begin with an
|
|
escape character, the terminal may appear to hang in no-
|
|
timeout mode after pressing the escape key until another
|
|
key is pressed.

|
|
The <STRONG>ungetch</STRONG> routine places <EM>ch</EM> back onto the input queue to
|
|
be returned by the next call to <STRONG>wgetch</STRONG>. There is just one
|
|
input queue for all windows.

The following special keys are defined in <STRONG><curses.h></STRONG>.
|
|
|
|
<STRONG>o</STRONG> Except for the special case <STRONG>KEY_RESIZE</STRONG>, it is neces-
|
|
sary to enable <STRONG>keypad</STRONG> for <STRONG>getch</STRONG> to return these codes.
|
|
|
|
<STRONG>o</STRONG> Not all of these are necessarily supported on any par-
|
|
ticular terminal.
|
|
|
|
<STRONG>o</STRONG> The naming convention may seem obscure, with some ap-
|
|
parent misspellings (such as "RSUME" for "resume").
|
|
The names correspond to the long terminfo capability
|
|
names for the keys, and were defined long ago, in the
|
|
1980s.

|
A few of these predefined values do <EM>not</EM> correspond to a
|
|
real key:
|
|
|
|
<STRONG>o</STRONG> <STRONG>KEY_RESIZE</STRONG> is returned when the <STRONG>SIGWINCH</STRONG> signal has
|
|
been detected (see <STRONG><A HREF="curs_initscr.3x.html">curs_initscr(3x)</A></STRONG> and <STRONG><A HREF="resizeterm.3x.html">resizeterm(3x)</A></STRONG>).
|
|
This code is returned whether or not <STRONG>keypad</STRONG> has been
|
|
enabled.
|
|
|
|
<STRONG>o</STRONG> <STRONG>KEY_MOUSE</STRONG> is returned for mouse-events (see
|
|
<STRONG><A HREF="curs_mouse.3x.html">curs_mouse(3x)</A></STRONG>). This code relies upon whether or not
|
|
<STRONG><A HREF="keypad.3x.html">keypad(3x)</A></STRONG> has been enabled, because (e.g., with <EM>xterm</EM>
|
|
mouse prototocol) ncurses must read escape sequences,
|
|
just like a function key.
|
|
|
|
|
|
</PRE><H3><a name="h3-Testing-key-codes">Testing key-codes</a></H3><PRE>
|
|
The <STRONG>has_key</STRONG> routine takes a key-code value from the above
|
|
list, and returns <STRONG>TRUE</STRONG> or <STRONG>FALSE</STRONG> according to whether the
|
|
current terminal type recognizes a key with that value.
|
|
|
|
The library also supports these extensions:
|
|
|
|
<STRONG>define_key</STRONG>
|
|
defines a key-code for a given string (see <STRONG>de-</STRONG>
|
|
<STRONG><A HREF="define_key.3x.html">fine_key(3x)</A></STRONG>).
|
|
|
|
<STRONG>key_defined</STRONG>
|
|
checks if there is a key-code defined for a given
|
|
string (see <STRONG><A HREF="key_defined.3x.html">key_defined(3x)</A></STRONG>).
|
|
|
|
|
|
</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
|
|
All routines return the integer <STRONG>ERR</STRONG> upon failure and an
|
|
integer value other than <STRONG>ERR</STRONG> (<STRONG>OK</STRONG> in the case of <STRONG>ungetch</STRONG>)
|
|
upon successful completion.
|
|
|
|
<STRONG>ungetch</STRONG>
|
|
returns ERR if there is no more room in the FIFO.
|
|
|
|
<STRONG>wgetch</STRONG>
|
|
returns ERR if the window pointer is null, or if
|
|
its timeout expires without having any data, or if
|
|
the execution was interrupted by a signal (<STRONG>errno</STRONG>
|
|
will be set to <STRONG>EINTR</STRONG>).
|
|
|
|
Functions with a "mv" prefix first perform a cursor move-
|
|
ment using <STRONG>wmove</STRONG>, and return an error if the position is
|
|
outside the window, or if the window pointer is null.
|
|
|
|
|
|
</PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE>
|
|
Use of the escape key by a programmer for a single charac-
|
|
ter function is discouraged, as it will cause a delay of
|
|
up to one second while the keypad code looks for a follow-
|
|
ing function-key sequence.
|
|
|
|
Some keys may be the same as commonly used control keys,
|
|
e.g., <STRONG>KEY_ENTER</STRONG> versus control/M, <STRONG>KEY_BACKSPACE</STRONG> versus
|
|
control/H. Some curses implementations may differ accord-
|
|
ing to whether they treat these control keys specially
|
|
(and ignore the terminfo), or use the terminfo defini-
|
|
tions. <STRONG>Ncurses</STRONG> uses the terminfo definition. If it says
|
|
that <STRONG>KEY_ENTER</STRONG> is control/M, <STRONG>getch</STRONG> will return <STRONG>KEY_ENTER</STRONG>
|
|
when you press control/M.
|
|
|
|
Generally, <STRONG>KEY_ENTER</STRONG> denotes the character(s) sent by the
|
|
<EM>Enter</EM> key on the numeric keypad:
|
|
|
|
<STRONG>o</STRONG> the terminal description lists the most useful keys,
|
|
|
|
<STRONG>o</STRONG> the <EM>Enter</EM> key on the regular keyboard is already han-
|
|
dled by the standard ASCII characters for carriage-re-
|
|
turn and line-feed,
|
|
|
|
<STRONG>o</STRONG> depending on whether <STRONG>nl</STRONG> or <STRONG>nonl</STRONG> was called, pressing
|
|
"Enter" on the regular keyboard may return either a
|
|
carriage-return or line-feed, and finally
|
|
|
|
<STRONG>o</STRONG> "Enter or send" is the standard description for this
|
|
key.
|
|
|
|
When using <STRONG>getch</STRONG>, <STRONG>wgetch</STRONG>, <STRONG>mvgetch</STRONG>, or <STRONG>mvwgetch</STRONG>, nocbreak
|
|
mode (<STRONG>nocbreak</STRONG>) and echo mode (<STRONG>echo</STRONG>) should not be used at
|
|
the same time. Depending on the state of the tty driver
|
|
when each character is typed, the program may produce un-
|
|
desirable results.
|
|
|
|
Note that <STRONG>getch</STRONG>, <STRONG>mvgetch</STRONG>, and <STRONG>mvwgetch</STRONG> may be macros.
|
|
|
|
Historically, the set of keypad macros was largely defined
|
|
by the extremely function-key-rich keyboard of the AT&T
|
|
7300, aka 3B1, aka Safari 4. Modern personal computers
|
|
usually have only a small subset of these. IBM PC-style
|
|
consoles typically support little more than <STRONG>KEY_UP</STRONG>,
|
|
<STRONG>KEY_DOWN</STRONG>, <STRONG>KEY_LEFT</STRONG>, <STRONG>KEY_RIGHT</STRONG>, <STRONG>KEY_HOME</STRONG>, <STRONG>KEY_END</STRONG>,
|
|
<STRONG>KEY_NPAGE</STRONG>, <STRONG>KEY_PPAGE</STRONG>, and function keys 1 through 12. The
|
|
Ins key is usually mapped to <STRONG>KEY_IC</STRONG>.

The *get* functions are described in the XSI Curses stan-
|
|
dard, Issue 4. They read single-byte characters only.
|
|
The standard specifies that they return <STRONG>ERR</STRONG> on failure,
|
|
but specifies no error conditions.
|
|
|
|
The echo behavior of these functions on input of <STRONG>KEY_</STRONG> or
|
|
backspace characters was not specified in the SVr4 docu-
|
|
mentation. This description is adopted from the XSI Curs-
|
|
es standard.
|
|
|
|
The behavior of <STRONG>getch</STRONG> and friends in the presence of han-
|
|
dled signals is unspecified in the SVr4 and XSI Curses
|
|
documentation. Under historical curses implementations,
|
|
it varied depending on whether the operating system's im-
|
|
plementation of handled signal receipt interrupts a
|
|
<STRONG>read(2)</STRONG> call in progress or not, and also (in some imple-
|
|
mentations) depending on whether an input timeout or non-
|
|
blocking mode has been set.
|
|
|
|
<STRONG>KEY_MOUSE</STRONG> is mentioned in XSI Curses, along with a few re-
|
|
lated terminfo capabilities, but no higher-level functions
|
|
use the feature. The implementation in ncurses is an ex-
|
|
tension.
|
|
|
|
<STRONG>KEY_RESIZE</STRONG> is an extension first implemented for ncurses.
|
|
NetBSD curses later added this extension.
|
|
|
|
Programmers concerned about portability should be prepared
|
|
for either of two cases: (a) signal receipt does not in-
|
|
terrupt <STRONG>getch</STRONG>; (b) signal receipt interrupts <STRONG>getch</STRONG> and
|
|
causes it to return ERR with <STRONG>errno</STRONG> set to <STRONG>EINTR</STRONG>.
|
|
|
|
The <STRONG>has_key</STRONG> function is unique to <STRONG>ncurses</STRONG>. We recommend
|
|
that any code using it be conditionalized on the <STRONG>NCURS-</STRONG>
|
|
<STRONG>ES_VERSION</STRONG> feature macro.
