+ 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.

<H2>RETURN VALUE</H2><PRE>

- than <STRONG>ERR</STRONG>") upon successful completion, unless otherwise
+ 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.
+ X/Open defines no error conditions. In this implementa-
+ tion, if the window parameter is null or the str parameter
+ is null, an error is returned.
+
+ Functions with a "mv" prefix first perform a cursor move-
+ ment using <STRONG>wmove</STRONG>, and return an error if the position is
+ outside the window, or if the window pointer is null.

<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).
+ These functions are described in the XSI Curses standard,
+ Issue 4, which adds const qualifiers to the arguments.
+
+ The Single Unix Specification, Version 2 states that
+ <STRONG>insnstr</STRONG> and <STRONG>winsnstr</STRONG> perform wrapping. This is probably
+ an error, since it makes this group of functions inconsis-
+ tent. Also, no implementation of curses documents this
+ inconsistency.
