72 These routines insert a character string (as many charac-
73 ters as will fit on the line) before the character under
74 the cursor. All characters to the right of the cursor are
75 shifted right with the possibility of the rightmost char-
76 acters on the line being lost. The cursor position does
77 not change (after moving to <EM>y</EM>, <EM>x</EM>, if specified). The
78 functions with <EM>n</EM> as the last argument insert a leading
79 substring of at most <EM>n</EM> characters. If <EM>n</EM><=0, then the
80 entire string is inserted.
82 Special characters are handled as in <STRONG>addch</STRONG>.
86 <H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
87 All routines that return an integer return <STRONG>ERR</STRONG> upon fail-
88 ure and OK (SVr4 specifies only "an integer value other
89 than <STRONG>ERR</STRONG>") upon successful completion, unless otherwise
90 noted in the preceding routine descriptions.
92 X/Open defines no error conditions. In this implementa-
93 tion, if the window parameter is null or the str parameter
94 is null, an error is returned.
96 Functions with a "mv" prefix first perform a cursor move-
97 ment using <STRONG>wmove</STRONG>, and return an error if the position is
98 outside the window, or if the window pointer is null.

103 Note that all but <STRONG>winsnstr</STRONG> may be macros.

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