</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
These routines insert the character <EM>ch</EM> before the character under the
cursor. All characters to the right of the cursor are moved one space
to the right, with the possibility of the rightmost character on the
line being lost. The insertion operation does not change the cursor
position.
</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
All routines that return an integer return <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG>
(SVr4 specifies only "an integer value other than <STRONG>ERR</STRONG>") upon successful
completion, unless otherwise noted in the preceding routine descrip-
tions.
Functions with a "mv" prefix first perform a cursor movement using
<STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
the window pointer is null.
</PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE>
These routines do not necessarily imply use of a hardware insert char-
acter feature.
Note that <STRONG>insch</STRONG>, <STRONG>mvinsch</STRONG>, and <STRONG>mvwinsch</STRONG> may be macros.
</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
These functions are described in the XSI Curses standard, Issue 4.
