<H2>DESCRIPTION</H2><PRE>
The effect of <STRONG>get_wstr</STRONG> is as though a series of calls to
<STRONG>get_wch</STRONG> were made, until a newline, other end-of-line, or
end-of-file condition is processed. An end-of-file condi-
tion is represented by <STRONG>WEOF</STRONG>, as defined in <STRONG><wchar.h></STRONG>. The
newline and end-of-line conditions are represented by the
<STRONG>\n</STRONG> <STRONG>wchar_t</STRONG> value. In all instances, the end of the string
is terminated by a null <STRONG>wchar_t</STRONG>. The routine places re-
sulting values in the area pointed to by <EM>wstr</EM>.
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).
The effect of <STRONG>wget_wstr</STRONG> is as though a series of calls to
<STRONG>wget_wch</STRONG> were made.
The effect of <STRONG>mvget_wstr</STRONG> is as though a call to <STRONG>move</STRONG> and
then a series of calls to <STRONG>get_wch</STRONG> were made.
The effect of <STRONG>mvwget_wstr</STRONG> is as though a call to <STRONG>wmove</STRONG> and
then a series of calls to <STRONG>wget_wch</STRONG> were made.
The <STRONG>getn_wstr</STRONG>, <STRONG>mvgetn_wstr</STRONG>, <STRONG>mvwgetn_wstr</STRONG>, and <STRONG>wgetn_wstr</STRONG>
functions are identical to the <STRONG>get_wstr</STRONG>, <STRONG>mvget_wstr</STRONG>,
<STRONG>mvwget_wstr</STRONG>, and <STRONG>wget_wstr</STRONG> functions, respectively, except
that the <STRONG>*n_*</STRONG> versions read at most <EM>n</EM> characters, letting
the application prevent overflow of the input buffer.
</PRE>
<H2>NOTES</H2><PRE>
Using <STRONG>get_wstr</STRONG>, <STRONG>mvget_wstr</STRONG>, <STRONG>mvwget_wstr</STRONG>, or <STRONG>wget_wstr</STRONG> to
read a line that overflows the array pointed to by <STRONG>wstr</STRONG>
causes undefined results. The use of <STRONG>getn_wstr</STRONG>,
<STRONG>mvgetn_wstr</STRONG>, <STRONG>mvwgetn_wstr</STRONG>, or <STRONG>wgetn_wstr</STRONG>, respectively, is
recommended.
These functions cannot return <STRONG>KEY_</STRONG> values because there is
no way to distinguish a <STRONG>KEY_</STRONG> value from a valid <STRONG>wchar_t</STRONG>
value.
All of these routines except <STRONG>wgetn_wstr</STRONG> may be macros.
</PRE>
<H2>RETURN VALUE</H2><PRE>
All of these functions return <STRONG>OK</STRONG> upon successful comple-
tion. Otherwise, they return <STRONG>ERR</STRONG>.
Functions using a window parameter return an error if it
is null.
<STRONG>wgetn_wstr</STRONG>
returns an error if the associated call to
<STRONG>wget_wch</STRONG> failed.
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>PORTABILITY</H2><PRE>
These functions are described in The Single Unix Specifi-
cation, Version 2. No error conditions are defined. This
implementation returns ERR if the window pointer is null,
or if the lower-level <STRONG>wget_wch</STRONG> call returns an ERR. In
the latter case, an ERR return without other data is
treated as an end-of-file condition, and the returned ar-
ray contains a <STRONG>WEOF</STRONG> followed by a null <STRONG>wchar_t</STRONG>.
X/Open curses documents these functions to pass an array
of <STRONG>wchar_t</STRONG>, but all of the vendors implement this using
<STRONG>wint_t</STRONG>.
