<H2>DESCRIPTION</H2><PRE>
These routines insert a character string (as many charac-
ters as will fit on the line) before the character under
the cursor. All characters to the right of the cursor are
shifted right, with the possibility of the rightmost char-
acters on the line being lost. The cursor position does
not change (after moving to <EM>y</EM>, <EM>x</EM>, if specified). The four
routines with <EM>n</EM> as the last argument insert a leading sub-
string of at most <EM>n</EM> characters. If <EM>n</EM><=0, then the entire
string is inserted.
If a character in <EM>str</EM> is a tab, newline, carriage return
or backspace, the cursor is moved appropriately within the
window. A newline also does a <STRONG>clrtoeol</STRONG> before moving.
Tabs are considered to be at every eighth column. If a
character in <EM>str</EM> is another control character, it is drawn
in the <STRONG>^</STRONG><EM>X</EM> notation. Calling <STRONG>winch</STRONG> after adding a control
character (and moving to it, if necessary) does not return
the control character, but instead returns a character in
the ^-representation of the control character.
</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>
Note that all but <STRONG>winsnstr</STRONG> may be macros.
</PRE>
<H2>PORTABILITY</H2><PRE>
These functions are described in the XSI Curses standard,
Issue 4, which adds const qualifiers to the arguments.
The XSI Curses error conditions <STRONG>EILSEQ</STRONG> and <STRONG>EILOVERFLOW</STRONG>
associated with extended-level conformance are not yet
detected (this implementation does not yet support XPG4
multibyte characters).
