.SH NAME
\fBinsstr\fR,
\fBint mvwinsnstr(WINDOW *win, int y, int x, const char *str, int n);\fR
.br
.SH DESCRIPTION
-These routines insert a character string (as many characters 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 characters
-on the line being lost. The cursor position does not change (after moving to
-\fIy\fR, \fIx\fR, if specified). The four routines with \fIn\fR as the last
-argument insert a leading substring of at most \fIn\fR characters. If
-\fIn\fR<=0, then the entire string is inserted.
-
-If a character in \fIstr\fR is a tab, newline, carriage return or
-backspace, the cursor is moved appropriately within the window. A
-newline also does a \fBclrtoeol\fR before moving. Tabs are considered
-to be at every eighth column. If a character in \fIstr\fR is another
-control character, it is drawn in the \fB^\fR\fIX\fR notation.
-Calling \fBwinch\fR 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.
+These routines insert a character string
+(as many characters 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 characters on the line being lost.
+The cursor position does not change
+(after moving to \fIy\fR, \fIx\fR, if specified).
+The functions with \fIn\fR as the last argument
+insert a leading substring of at most \fIn\fR characters.
+If \fIn\fR<=0, then the entire string is inserted.
+.PP
+Special characters are handled as in \fBaddch\fP.
.SH RETURN VALUE
All routines that return an integer return \fBERR\fR upon failure and OK (SVr4
specifies only "an integer value other than \fBERR\fR") upon successful
completion, unless otherwise noted in the preceding routine descriptions.
+.PP
+X/Open defines no error conditions.
+In this implementation,
+if the window parameter is null or the str parameter is null,
+an error is returned.
.SH NOTES
Note that all but \fBwinsnstr\fR may be macros.
.SH PORTABILITY
These functions are described in the XSI Curses standard, Issue 4, which adds
-const qualifiers to the arguments. The XSI Curses error conditions
-\fBEILSEQ\fR and \fBEILOVERFLOW\fR associated with extended-level conformance
-are not yet detected (this implementation does not yet support XPG4 multi-byte
-characters).
+const qualifiers to the arguments.
+.LP
+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.
