.SH DESCRIPTION
These routines insert a character string
(as many characters as will fit on the line)
before the character under the cursor,
as if calling \fB\%winsch\fP(3NCURSES).
All characters to the right of the cursor are shifted right,
with the possibility of the rightmost characters on the line being lost.
No wrapping is performed.
.PP
The cursor position does not change
(after moving to \fIy\fP, \fIx\fP, if specified).
.PP
The functions with \fIn\fP as the last argument
insert a leading substring of at most \fIn\fP characters.
If \fIn\fP is less than zero, the entire string is inserted
(stopping on a NUL character).
.PP
Special characters are handled as in \fB\%waddch\fP(3NCURSES).
.SH RETURN VALUE
All functions return the integer \fBERR\fP upon failure and \fBOK\fP on success.
.PP
X/Open Curses does not specify any error conditions.
This implementation returns an error
.bP
if the \fIwin\fP parameter is null or
.bP
if the \fIstr\fP parameter is null or
.bP
the \fB\%winsch\fP(3NCURSES) function returns an error.
.PP
Functions prefixed with \*(``mv\*('' first perform cursor movement and
fail if the position
.RI ( y ,
.IR x )
is outside the window boundaries.
.SH NOTES
All but \fBwinsnstr\fP may be macros.
.SH PORTABILITY
These functions are described in X/Open Curses, Issue 4,
which adds \fI\%const\fP qualifiers to the arguments.
.PP
The Single Unix Specification, Version 2 states that
\fBinsnstr\fP and \fBwinsnstr\fP perform wrapping.
This is probably an error, since it makes this group of functions inconsistent.
Also, no implementation of curses documents this inconsistency.
.PP
X/Open states that the entire string is inserted if \fIn\fP is less than 1.
This is probably an error,
because it is inconsistent with other functions,
and differs from the SVr4 and X/Open implementations on Solaris.
