<H2>NAME</H2><PRE>
       <STRONG>insch</STRONG>,  <STRONG>winsch</STRONG>,  <STRONG>mvinsch</STRONG>,  <STRONG>mvwinsch</STRONG>  -  insert a character
       before cursor in a <STRONG>curses</STRONG> window


</PRE>
<H2>SYNOPSIS</H2><PRE>
       <STRONG>#include</STRONG> <STRONG>&lt;curses.h&gt;</STRONG>

       <STRONG>int</STRONG> <STRONG>insch(chtype</STRONG> <STRONG>ch);</STRONG>
       <STRONG>int</STRONG> <STRONG>winsch(WINDOW</STRONG> <STRONG>*win,</STRONG> <STRONG>chtype</STRONG> <STRONG>ch);</STRONG>
       <STRONG>int</STRONG> <STRONG>mvinsch(int</STRONG> <STRONG>y,</STRONG> <STRONG>int</STRONG> <STRONG>x,</STRONG> <STRONG>chtype</STRONG> <STRONG>ch);</STRONG>
       <STRONG>int</STRONG> <STRONG>mvwinsch(WINDOW</STRONG> <STRONG>*win,</STRONG> <STRONG>int</STRONG> <STRONG>y,</STRONG> <STRONG>int</STRONG> <STRONG>x,</STRONG> <STRONG>chtype</STRONG> <STRONG>ch);</STRONG>


</PRE>
<H2>DESCRIPTION</H2><PRE>
       These routines insert the character <EM>ch</EM> before the  charac-
       ter  under the cursor.  All characters to the right of the
       cursor are moved one space to the right, with  the  possi-
       bility  of the rightmost character on the line being lost.
       The insertion operation does not change the  cursor  posi-
       tion.


</PRE>
<H2>RETURN VALUE</H2><PRE>
       All  routines that return an integer return <STRONG>ERR</STRONG> upon fail-
       ure and OK (SVr4 specifies only "an  integer  value  other
       than  <STRONG>ERR</STRONG>")  upon  successful completion, unless otherwise
       noted in the preceding routine descriptions.


</PRE>
<H2>NOTES</H2><PRE>
       These routines do not necessarily imply use of a  hardware
       insert character feature.

       Note that <STRONG>insch</STRONG>, <STRONG>mvinsch</STRONG>, and <STRONG>mvwinsch</STRONG> may be macros.


</PRE>
<H2>PORTABILITY</H2><PRE>
       These  functions are described in the XSI Curses standard,
       Issue 4.
