67        These routines insert a character string (as many  characters  as  will
68        fit on the line) before the character under the cursor.  All characters
69        to the right of the cursor are shifted right with  the  possibility  of
70        the  rightmost  characters on the line being lost.  The cursor position
71        does not change (after moving to <EM>y</EM>, <EM>x</EM>, if  specified).   The  functions
72        with  <EM>n</EM>  as  the  last argument insert a leading substring of at most <EM>n</EM>
73        characters.  If <EM>n</EM>&lt;=0, then the entire string is inserted.
74
75        Special characters are handled as in <STRONG>addch</STRONG>.
76
77
78 </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
79        All routines that return an integer return  <STRONG>ERR</STRONG>  upon  failure  and  <STRONG>OK</STRONG>
80        (SVr4 specifies only "an integer value other than <STRONG>ERR</STRONG>") upon successful
81        completion, unless otherwise noted in the  preceding  routine  descrip-
82        tions.
83
84        X/Open  defines  no  error  conditions.  In this implementation, if the
85        window parameter is null or the str parameter  is  null,  an  error  is
86        returned.
87
88        Functions  with  a  "mv"  prefix  first perform a cursor movement using
89        <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
90        the window pointer is null.

98        These  functions  are  described  in  the XSI Curses standard, Issue 4,
99        which adds const qualifiers to the arguments.
100
101        The Single Unix Specification, Version 2 states that <STRONG>insnstr</STRONG>  and  <STRONG>win-</STRONG>
102        <STRONG>snstr</STRONG> perform wrapping.  This is probably an error, since it makes this
103        group of functions inconsistent.  Also,  no  implementation  of  curses
104        documents this inconsistency.
