</PRE>
<H2>DESCRIPTION</H2><PRE>
       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 point-
       ed to by the character pointer <EM>str</EM>.

       <STRONG>wgetnstr</STRONG>  reads  at  most  <EM>n</EM> characters, thus preventing a
       possible overflow of the input buffer.  Any attempt to en-
       ter more characters (other than the terminating newline or
       carriage return) causes a beep.  Function keys also  cause
       a  beep  and are ignored.  The <STRONG>getnstr</STRONG> function reads from
       the <EM>stdscr</EM> default window.

       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.

       Characters  input are echoed only if <STRONG>echo</STRONG> is currently on.
       In that case, backspace is echoed as deletion of the  pre-
       vious character (typically a left motion).


</PRE>
<H2>RETURN VALUE</H2><PRE>
       All routines return the integer <STRONG>ERR</STRONG> upon failure and an <STRONG>OK</STRONG>
       (SVr4 specifies only "an integer value  other  than  <STRONG>ERR</STRONG>")
       upon successful completion.

       X/Open defines no error conditions.

       In this implementation, these functions return an error if
       the window pointer is null,  or  if  its  timeout  expires
       without having any data.

       This  implementation  provides an extension as well.  If a
       SIGWINCH interrupts the function, it will  return  <STRONG>KEY_RE-</STRONG>
       <STRONG>SIZE</STRONG> rather than <STRONG>OK</STRONG> or <STRONG>ERR</STRONG>.


</PRE>
<H2>NOTES</H2><PRE>
       Note that <STRONG>getstr</STRONG>, <STRONG>mvgetstr</STRONG>, and <STRONG>mvwgetstr</STRONG> may be macros.


</PRE>
<H2>PORTABILITY</H2><PRE>
       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 im-
       plementation returns ERR if the window pointer is null, or
       if the lower-level <STRONG>wgetch</STRONG> call returns an ERR.

       SVr3  and early SVr4 curses implementations did not reject
       function keys; the SVr4.0 documentation claimed that "spe-
       cial  keys"  (such  as  function keys, "home" key, "clear"
       key, <EM>etc</EM>.) are "interpreted", without 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).

       The functions  <STRONG>getnstr</STRONG>,  <STRONG>mvgetnstr</STRONG>,  and  <STRONG>mvwgetnstr</STRONG>  were
       present but not documented in SVr4.
