+.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 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.
+.PP
+Functions with a "mv" prefix first perform a cursor movement using
+\fBwmove\fP, and return an error if the position is outside the window,
+or if the window pointer is null.
+.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.
+.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.
