<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,
|
|
