</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
<STRONG>wins_wstr</STRONG> inserts a wide-character string <EM>wstr</EM> before the character at
the cursor in window <EM>win</EM> as if by calling <STRONG><A HREF="curs_ins_wch.3x.html">wins_wch(3x)</A></STRONG> for each <EM>wchar</EM><STRONG>_</STRONG><EM>t</EM>
in <EM>wstr</EM>. No line wrapping is performed. Characters to the right of
the cursor are shifted right; those at the right edge of the window may
be lost. <STRONG>wins_wstr</STRONG> stops inserting if it would have to wrap to the
next line to write the next <EM>wchar</EM><STRONG>_</STRONG><EM>t</EM> in <EM>wstr</EM>. The cursor position does
not change (after moving to (<EM>y</EM>, <EM>x</EM>), if specified). <STRONG>wins_nwstr</STRONG> does the
same, but inserts at most <EM>n</EM> wide characters, or as many as possible (up
to the end of the line) if <EM>n</EM> is negative. <STRONG><A HREF="ncurses.3x.html">ncurses(3x)</A></STRONG> describes the
variants of these functions.
</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
These functions return <STRONG>OK</STRONG> on success and <STRONG>ERR</STRONG> on failure.
In <EM>ncurses</EM>, they return <STRONG>ERR</STRONG> if
<STRONG>o</STRONG> <EM>win</EM> is <EM>NULL</EM>,
<STRONG>o</STRONG> <EM>wstr</EM> is <EM>NULL</EM>,
<STRONG>o</STRONG> the first wide character in <EM>wstr</EM> is a non-spacing character, or
<STRONG>o</STRONG> an internal <STRONG><A HREF="curs_ins_wch.3x.html">wins_wch(3x)</A></STRONG> call returns <STRONG>ERR</STRONG>.
Functions prefixed with "mv" first perform cursor movement and fail if
the position (<EM>y</EM>, <EM>x</EM>) is outside the window boundaries.
</PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE>
All of these functions except <STRONG>wins_nwstr</STRONG> may be implemented as macros.
</PRE><H2><a name="h2-EXTENSIONS">EXTENSIONS</a></H2><PRE>
<STRONG>ins_nwstr</STRONG>, <STRONG>wins_nwstr</STRONG>, <STRONG>mvins_nwstr</STRONG>, and <STRONG>mvwins_nwstr</STRONG>'s acceptance of
negative <EM>n</EM> values is an <EM>ncurses</EM> extension.
</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
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.
X/Open Curses does not specify what happens if a non-spacing character
follows a control character.
Issue 4 states that the entire string is inserted if <EM>n</EM> is less than 1.
This is probably an error, because it is inconsistent with other
functions such as <EM>waddwstr</EM>, and differs from the SVr4 <EM>curses</EM> and
Solaris <EM>xcurses</EM> implementations. Nevertheless, Issue 7 retains the
language.
</PRE><H2><a name="h2-HISTORY">HISTORY</a></H2><PRE>
X/Open Curses Issue 4 (1995) initially specified these functions. The
System V Interface Definition Version 4 (1995), specified functions
named <EM>winswstr</EM> and <EM>winsnwstr</EM> (and the usual variants). These were
later additions to SVr4.<EM>x</EM>, not appearing in the first SVr4 (1989).
They differ from X/Open's later <EM>wins</EM><STRONG>_</STRONG><EM>wstr</EM> and <EM>wins</EM><STRONG>_</STRONG><EM>nwstr</EM> in that their
<EM>wstr</EM> parameters are not <EM>const</EM>-qualified.
