-       The function <STRONG>getstr</STRONG> is equivalent to a series of calls to <STRONG>getch</STRONG>,  until
-       a  newline or carriage return is received (the terminating character is
-       not included in the returned string).  The resulting value is placed in
-       the area pointed to by the character pointer <EM>str</EM>.
+       <STRONG>wgetstr</STRONG> populates a  user-supplied  string  buffer  <EM>str</EM>  by  repeatedly
+       calling  <STRONG><A HREF="curs_getch.3x.html">wgetch(3x)</A></STRONG> with the <EM>win</EM> argument until a line feed or carriage
+       return character is input.  The function
+
+       <STRONG>o</STRONG>   does not copy the terminating character to <EM>str</EM>;
+
+       <STRONG>o</STRONG>   always terminates <EM>str</EM> with a null character;
+
+       <STRONG>o</STRONG>   interprets  the   screen's   erase   and   kill   characters   (see
+           <STRONG><A HREF="curs_termattrs.3x.html">erasechar(3x)</A></STRONG> and <STRONG><A HREF="curs_termattrs.3x.html">killchar(3x)</A></STRONG>);
+
+       <STRONG>o</STRONG>   recognizes  function  keys  only  if  the screen's keypad option is
+           enabled (see <STRONG><A HREF="curs_inopts.3x.html">keypad(3x)</A></STRONG>);
+
+       <STRONG>o</STRONG>   treats the function keys <STRONG>KEY_LEFT</STRONG> and <STRONG>KEY_BACKSPACE</STRONG> the same as the
+           erase character; and
+
+       <STRONG>o</STRONG>   discards  function key inputs other than those treated as the erase
+           character, calling <STRONG><A HREF="curs_beep.3x.html">beep(3x)</A></STRONG>.
+
+       The erase character replaces the character at the  end  of  the  buffer
+       with  a  null character, while the kill character does the same for the
+       entire buffer.
+
+       If the screen's echo option is enabled (see <STRONG><A HREF="curs_inopts.3x.html">echo(3x)</A></STRONG>), <STRONG>wgetstr</STRONG>  updates
+       <EM>win</EM> with <STRONG><A HREF="curs_addch.3x.html">wechochar(3x)</A></STRONG>.  Further,
 
 
-       <STRONG>wgetnstr</STRONG>  reads  at most <EM>n</EM> characters, thus preventing a possible over-
-       flow of the input buffer.  Any attempt to enter more characters  (other
-       than  the terminating newline or carriage return) causes a beep.  Func-
-       tion keys also cause a beep and  are  ignored.   The  <STRONG>getnstr</STRONG>  function
-       reads from the <EM>stdscr</EM> default window.
+       <STRONG>o</STRONG>   the  erase  character and its function key synonyms move the cursor
+           to the left, and
 
 
-       The  user's  erase and kill characters are interpreted.  If keypad mode
-       is on for the window, <STRONG>KEY_LEFT</STRONG> and <STRONG>KEY_BACKSPACE</STRONG>  are  both  considered
-       equivalent to the user's kill character.
+       <STRONG>o</STRONG>   the kill character returns the cursor to where it was located  when
+           <STRONG>wgetstr</STRONG> was called.
 
 
-       Characters  input  are  echoed  only  if <STRONG>echo</STRONG> is currently on.  In that
-       case, backspace is echoed as deletion of the previous character  (typi-
-       cally a left motion).
+       <STRONG>wgetnstr</STRONG>  is  similar,  but  reads  at  most  <EM>n</EM>  characters, aiding the
+       application to avoid overrunning the buffer to which  <EM>str</EM>  points.   An
+       attempt  to  input  more  than <EM>n</EM> characters (other than the terminating
+       line feed or carriage return) is ignored with a beep.

-       fies only "an integer value other than <STRONG>ERR</STRONG>")  upon  successful  comple-
-       tion.
+       These functions return <STRONG>OK</STRONG> on success and <STRONG>ERR</STRONG> on failure.

-       This implementation provides an extension as well.  If a  <STRONG>SIGWINCH</STRONG>  in-
-       terrupts the function, it will return <STRONG>KEY_RESIZE</STRONG> rather than <STRONG>OK</STRONG> or <STRONG>ERR</STRONG>.
+       Further, in <EM>ncurses</EM>, these functions return <STRONG>KEY_RESIZE</STRONG>  if  a  <STRONG>SIGWINCH</STRONG>
+       event interrupts the function.
 
 
-       Functions  with  a  "mv"  prefix  first perform a cursor movement using
-       <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
-       the window pointer is null.
+       Functions  prefixed with "mv" first perform cursor movement and fail if
+       the position (<EM>y</EM>, <EM>x</EM>) is outside the window boundaries.

+
+       While <STRONG>wgetnstr</STRONG> is conceptually a series of calls  to  <STRONG>wgetch</STRONG>,  it  also
+       temporarily  changes  properties  of the <EM>curses</EM> screen to permit simple
+       editing of the input buffer.  It saves  the  screen's  state  and  then
+       calls  <STRONG><A HREF="curs_inopts.3x.html">nl(3x)</A></STRONG>  and,  if  the  screen  was  in  normal  ("cooked") mode,
+       <STRONG><A HREF="curs_inopts.3x.html">cbreak(3x)</A></STRONG>.  Before returning, it  restores  the  saved  screen  state.

-       These  functions  are  described  in  the XSI Curses standard, Issue 4.
-       They read single-byte characters only.  The standard  does  not  define
-       any  error  conditions.   This implementation returns <STRONG>ERR</STRONG> if the window
-       pointer is null, or if the lower-level <STRONG><A HREF="curs_getch.3x.html">wgetch(3x)</A></STRONG> call returns an <STRONG>ERR</STRONG>.
+       Applications employing <EM>ncurses</EM> extensions should condition their use on
+       the visibility of the <STRONG>NCURSES_VERSION</STRONG> preprocessor macro.
+
+       X/Open Curses Issue 4 describes these functions.  It specifies no error
+       conditions  for them, but indicates that <EM>wgetnstr</EM> and its variants read
+       "the entire multi-byte sequence associated with a character" and "fail"
+       if <EM>n</EM> and <EM>str</EM> together do not describe a buffer "large enough to contain
+       any complete characters".   In  <EM>ncurses</EM>,  however,  <EM>wgetch</EM>  reads  only
+       single-byte characters, so this scenario does not arise.
+
+       SVr4  <EM>curses</EM>  describes  a  successful return value only as "an integer
+       value other than <STRONG>ERR</STRONG>".
+
+       SVr3 and early SVr4 <EM>curses</EM>  implementations  did  not  reject  function
+       keys; the SVr4 documentation asserted that, like the screen's erase and
+       kill characters, they were
+
+              interpreted, as well as any special keys (such as function keys,
+              "home" key, "clear" key, <EM>etc.</EM>)
 
 
-       SVr3 and early SVr4 curses  implementations  did  not  reject  function
-       keys;  the  SVr4.0  documentation  claimed that "special keys" (such as
-       function keys, "home" key, "clear" key, <EM>etc</EM>.) are "interpreted",  with-
-       out  giving details.  It lied.  In fact, the "character" value appended
-       to the string by those implementations was predictable but  not  useful
-       (being, in fact, the low-order eight bits of the key's KEY_ value).
+       without  further  detail.   It  lied.   In  fact, the "character" value
+       appended to the string by those implementations was predictable but not
+       useful  --  being,  in fact, the low-order eight bits of the key code's
+       <STRONG>KEY_</STRONG> constant value.  (The same language, unchanged except for styling,
+       survived into X/Open Curses Issue 4, but disappeared from Issue 7.)
 
 
-       The  functions  <STRONG>getnstr</STRONG>, <STRONG>mvgetnstr</STRONG>, and <STRONG>mvwgetnstr</STRONG> were present but not
-       documented in SVr4.
+       X/Open  Curses Issue 5 (2007) stated that these functions "read at most
+       <EM>n</EM> bytes" but did not  state  whether  the  terminating  null  character
+       counted  toward  that limit.  X/Open Curses Issue 7 (2009) changed that
+       to say they "read at most <EM>n</EM>-1 bytes" to allow for the terminating  null
+       character.  As of 2018, some implementations count it, some do not.
+
+       <STRONG>o</STRONG>   <EM>ncurses</EM> 6.1 and <EM>PDCurses</EM> do not count the null character toward the
+           limit, while Solaris and NetBSD <EM>curses</EM> do.
+
+       <STRONG>o</STRONG>   Solaris  <EM>xcurses</EM>  offers   both   behaviors:   its   wide-character
+           <EM>wgetn</EM><STRONG>_</STRONG><EM>wstr</EM>  reserves  room  for a wide null character, but its non-
+           wide <EM>wgetnstr</EM> does not consistently count a null  character  toward
+           the limit.
+
+       In SVr4 <EM>curses</EM>, a negative <EM>n</EM> tells <EM>wgetnstr</EM> to assume that the caller's
+       buffer is large enough to hold the result; that is, the  function  then
+       acts  like  <EM>wgetstr</EM>.   X/Open Curses does not mention this behavior (or
+       anything  related  to  nonpositive  <EM>n</EM>  values),  however  most   <EM>curses</EM>
+       libraries  implement  it.  Most implementations nevertheless enforce an
+       upper limit on the count of bytes they write to the destination  buffer
+       <EM>str</EM>.
+
+       <STRONG>o</STRONG>   BSD   <EM>curses</EM>   lacked  <EM>wgetnstr</EM>,  and  its  <EM>wgetstr</EM>  wrote  to  <EM>str</EM>
+           unboundedly, as did that in SVr2.
+
+       <STRONG>o</STRONG>   <EM>PDCurses</EM>, and SVr3.1, SVr4, and Solaris <EM>curses</EM> limit both functions
+           to  writing  256  bytes.  Other System V-based platforms likely use
+           the same limit.
+
+       <STRONG>o</STRONG>   Solaris <EM>xcurses</EM> limits the write to <STRONG>LINE_MAX</STRONG> bytes.
+
+       <STRONG>o</STRONG>   NetBSD 7 <EM>curses</EM> imposes no particular limit on the  length  of  the
+           write,  but does validate <EM>n</EM> to ensure that it is greater than zero.
+           A comment in NetBSD's source  code  asserts  that  SUSv2  specifies
+           this.
+
+       <STRONG>o</STRONG>   <EM>ncurses</EM>  prior  to 6.2 (2020) imposes no limit on the length of the
+           write, and treats <EM>wgetnstr</EM>'s <EM>n</EM> parameter as SVr4 <EM>curses</EM> does.
+
+       <STRONG>o</STRONG>   <EM>ncurses</EM> 6.2 uses <STRONG>LINE_MAX</STRONG>  or  a  larger  (system-dependent)  value
+           provided  by  <STRONG>sysconf(3)</STRONG>.   If  neither  <STRONG>LINE_MAX</STRONG>  nor  <EM>sysconf</EM>  is
+           available, <EM>ncurses</EM>  uses  the  POSIX  minimum  value  for  <STRONG>LINE_MAX</STRONG>
+           (2048).   In  either  case,  it reserves a byte for the terminating
+           null character.
+
+       Implementations vary in their handling of input control characters.
+
+       <STRONG>o</STRONG>   While they may enable the screen's echo option, some do not take it
+           out  of  raw  mode,  and  may  take  cbreak  mode into account when
+           deciding whether to handle echoing within <EM>wgetnstr</EM> or to rely on it
+           as a side effect of calling <EM>wgetch</EM>.
+
+       <STRONG>o</STRONG>   Originally,  <EM>ncurses</EM>, like its progenitor <EM>pcurses</EM>, had its <EM>wgetnstr</EM>
+           call <EM>noraw</EM> and <EM>cbreak</EM> before accepting input.  That may  have  been
+           done  to  make  function keys work; it is not necessary with modern
+           <EM>ncurses</EM>.
+
+           Since 1995, <EM>ncurses</EM> has provided handlers for <STRONG>SIGINTR</STRONG>  and  <STRONG>SIGQUIT</STRONG>
+           events,  which  are typically generated at the keyboard with <STRONG>^C</STRONG> and
+           <STRONG>^\</STRONG> respectively.  In cbreak mode, those handlers catch a signal and
+           stop   the  program,  whereas  other  implementations  write  those
+           characters into the buffer.
+
+       <STRONG>o</STRONG>   Starting with <EM>ncurses</EM> 6.3 (2021), <EM>wgetnstr</EM> preserves  raw  mode  if
+           the  screen  was  already  in that state, allowing one to enter the
+           characters the terminal interprets as  interrupt  and  quit  events
+           into the buffer, for better compatibility with SVr4 <EM>curses</EM>.
