All characters to the right of the cursor are shifted 71 right, with the possibility of the rightmost characters on the line 72 being lost. No wrapping is performed. 73 74 The cursor position does not change (after moving to <EM>y</EM>, <EM>x</EM>, if 75 specified). 76 77 The functions with <EM>n</EM> as the last argument insert a leading substring of 78 at most <EM>n</EM> characters. If <EM>n</EM> is less than zero, the entire string is 79 inserted (stopping on a NUL character). 80 81 Special characters are handled as in <STRONG><A HREF="curs_addch.3x.html">waddch(3x)</A></STRONG>. 82 83 84</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE> 85 All functions return the integer <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG> on success. 86 87 X/Open Curses does not specify any error conditions.

This is probably an error, since it makes 110 this group of functions inconsistent. Also, no implementation of 111 curses documents this inconsistency. 112 113 X/Open states that the entire string is inserted if <EM>n</EM> is less than 1. 114 This is probably an error, because it is inconsistent with other 115 functions, and differs from the SVr4 and X/Open implementations on 116 Solaris. 117 118 119</PRE><H2><a name="h2-SEE-ALSO">SEE ALSO</a></H2><PRE> 120 <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG>, <STRONG><A HREF="curs_inch.3x.html">curs_inch(3x)</A></STRONG>, <STRONG><A HREF="curs_ins_wstr.3x.html">curs_ins_wstr(3x)</A></STRONG>, <STRONG><A HREF="curs_util.3x.html">curs_util(3x)</A></STRONG> 121 122 123 124ncurses 6.5 2024-04-20 <STRONG><A HREF="curs_insstr.3x.html">curs_insstr(3x)</A></STRONG> 125</PRE> 126<div class="nav"> 127<ul> 128<li><a href="#h2-NAME">NAME</a></li> 129<li><a href="#h2-SYNOPSIS">SYNOPSIS</a></li> 130<li><a href="#h2-DESCRIPTION">DESCRIPTION</a></li> 131<li><a href="#h2-RETURN-VALUE">RETURN VALUE</a></li> 132<li><a href="#h2-NOTES">NOTES</a></li> 133<li><a href="#h2-PORTABILITY">PORTABILITY</a></li> 134<li><a href="#h2-SEE-ALSO">SEE ALSO</a></li> 135</ul> 136</div> 137</BODY> 138</HTML> 139
