.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.
+.B \%winsstr
+inserts a string
+.I str
+before the character at the cursor in window
+.I win
+as if by calling \fBwinsch\fP(3X) for each
+.I char
+in
+.IR str "."
+No line wrapping is performed.
+Characters to the right of the cursor are shifted right;
+those at the right edge of the window may be lost.
+.B \%winsstr
+stops inserting if it would have to wrap to the next line to write the
+next
+.I \%char
+in
+.IR str "."
+The cursor position does not change
+(after moving to
+.RI ( y ","
+.IR x "),"
+if specified).
+.B \%insnstr
+does the same,
+but inserts at most
+.I n
+characters,
+or as many as possible
+(up to the end of the line)
+if
+.I n
+is
+.BR \-1 "."
+\fB\%ncurses\fP(3X) describes the variants of these functions.
.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.
+These functions return
+.B OK
+on success and
+.B ERR
+on failure.
+.PP
+In
+.IR \%ncurses ","
+they return
+.B ERR
+if
+.bP
+.I win
+is
+.BR NULL ","
+.bP
+.I str
+is
+.BR NULL ","
+or
+.bP
+an internal \fBwinsch\fP(3X) call returns
+.BR ERR "."
+.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
-Note that all but \fBwinsnstr\fR may be macros.
+All of these functions except
+.B \%winsnstr
+may be implemented as 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).
+X/Open Curses,
+Issue 4 describes these functions.
+It specifies no error conditions for them.
+.PP
+Issue 4 distinguished
+.B \%insnstr
+and
+.B \%winsnstr
+from the other functions documented above
+by stating they \*(``do not perform wrapping\*(''.
+This was probably an error,
+since it makes this group of functions inconsistent.
+No implementation of
+.I curses
+documents this inconsistency,
+and Issue 7 removed it.
+.PP
+Issue 4 states that the entire string is inserted if
+.I n
+is less than 1.
+This is probably an error,
+.\" ...copied from SVID 4, which made the same error; see p. 510.
+because it is inconsistent with other functions
+such as \fB\%waddstr\fP(3X),
+and differs from the SVr4
+.I curses
+and Solaris
+.I xcurses
+implementations.
+Nevertheless,
+Issue 7 retains the language.
