68        The  effect  of <STRONG>get_wstr</STRONG> is as though a series of calls to
69        <STRONG><A HREF="curs_get_wch.3x.html">get_wch(3x)</A></STRONG> were made, until a newline, other end-of-line,
70        or  end-of-file  condition  is  processed.  An end-of-file
71        condition is represented by <STRONG>WEOF</STRONG>, as defined in <STRONG>&lt;wchar.h&gt;</STRONG>.
72        The  newline and end-of-line conditions are represented by
73        the <STRONG>\n</STRONG> <STRONG>wchar_t</STRONG> value.  In all instances, the  end  of  the
74        string  is  terminated  by  a  null  <STRONG>wchar_t</STRONG>.  The routine
75        places resulting values in the area pointed to by <EM>wstr</EM>.
76
77        The user's erase and kill characters are interpreted.   If
78        keypad   mode   is   on   for  the  window,  <STRONG>KEY_LEFT</STRONG>  and
79        <STRONG>KEY_BACKSPACE</STRONG> are both considered equivalent to the user's
80        kill character.
81
82        Characters  input are echoed only if <STRONG>echo</STRONG> is currently on.
83        In that case, backspace is echoed as deletion of the  pre-
84        vious character (typically a left motion).
85
86        The  effect of <STRONG>wget_wstr</STRONG> is as though a series of calls to
87        <STRONG>wget_wch</STRONG> were made.
88
89        The effect of <STRONG>mvget_wstr</STRONG> is as though a call to  <STRONG>move</STRONG>  and
90        then a series of calls to <STRONG>get_wch</STRONG> were made.
91
92        The effect of <STRONG>mvwget_wstr</STRONG> is as though a call to <STRONG>wmove</STRONG> and
93        then a series of calls to <STRONG>wget_wch</STRONG> were made.
94
95        The <STRONG>getn_wstr</STRONG>, <STRONG>mvgetn_wstr</STRONG>, <STRONG>mvwgetn_wstr</STRONG>,  and  <STRONG>wgetn_wstr</STRONG>
96        functions  are  identical  to  the  <STRONG>get_wstr</STRONG>,  <STRONG>mvget_wstr</STRONG>,
97        <STRONG>mvwget_wstr</STRONG>, and <STRONG>wget_wstr</STRONG> functions, respectively, except
98        that  the <STRONG>*n_*</STRONG> versions read at most <EM>n</EM> characters, letting
99        the application prevent overflow of the input buffer.

102 </PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE>
103        Using <STRONG>get_wstr</STRONG>, <STRONG>mvget_wstr</STRONG>, <STRONG>mvwget_wstr</STRONG>, or  <STRONG>wget_wstr</STRONG>  to
104        read  a  line  that overflows the array pointed to by <STRONG>wstr</STRONG>
105        causes  undefined  results.    The   use   of   <STRONG>getn_wstr</STRONG>,
106        <STRONG>mvgetn_wstr</STRONG>, <STRONG>mvwgetn_wstr</STRONG>, or <STRONG>wgetn_wstr</STRONG>, respectively, is
107        recommended.
108
109        These functions cannot return <STRONG>KEY_</STRONG> values because there is
110        no  way  to  distinguish a <STRONG>KEY_</STRONG> value from a valid <STRONG>wchar_t</STRONG>
111        value.
112
113        All of these routines except <STRONG>wgetn_wstr</STRONG> may be macros.
114
115
116 </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
117        All of these functions return <STRONG>OK</STRONG> upon  successful  comple-
118        tion.  Otherwise, they return <STRONG>ERR</STRONG>.
119
120        Functions  using  a window parameter return an error if it
121        is null.
122
123               <STRONG>wgetn_wstr</STRONG>
124                    returns an error if  the  associated  call  to
125                    <STRONG>wget_wch</STRONG> failed.
126
127        Functions  with a "mv" prefix first perform a cursor move-
128        ment using <STRONG>wmove</STRONG>, and return an error if the  position  is
129        outside the window, or if the window pointer is null.
130
131
132 </PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
133        These  functions are described in The Single Unix Specifi-
134        cation, Version 2.  No error conditions are defined.  This
135        implementation  returns ERR if the window pointer is null,
136        or if the lower-level <STRONG>wget_wch</STRONG> call returns  an  ERR.   In
137        the  latter  case,  an  ERR  return  without other data is
138        treated as an end-of-file condition, and the returned  ar-
139        ray contains a <STRONG>WEOF</STRONG> followed by a null <STRONG>wchar_t</STRONG>.
140
141        X/Open  curses documented these functions to pass an array
142        of <STRONG>wchar_t</STRONG> in 1997, but that was an error because of  this
143        part of the description:
144
145               The  effect  of <EM>get</EM><STRONG>_</STRONG><EM>wstr()</EM> is as though a series of
146               calls to <EM>get</EM><STRONG>_</STRONG><EM>wch()</EM> were made, until a newline char-
147               acter,  end-of-line character, or end-of-file char-
148               acter is processed.
149
150        The latter function <EM>get</EM><STRONG>_</STRONG><EM>wch()</EM> can return a negative value,
151        while  <STRONG>wchar_t</STRONG> is a unsigned type.  All of the vendors im-
152        plement this using <STRONG>wint_t</STRONG>, following the standard.
