int winsstr(WINDOW *win, const char *str);
int winsnstr(WINDOW *win, const char *str, int n);
int mvinsstr(int y, int x, const char *str);
int mvinsnstr(int y, int x, const char *str, int n);

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 y, x, if specified). The four routines
with n as the last argument insert a leading substring of at most n
characters. If n<=0, then the entire string is inserted.
If a character in str is a tab, newline, carriage return or backspace,
the cursor is moved appropriately within the window. A newline also
does a clrtoeol before moving. Tabs are considered to be at every
eighth column. If a character in str is another control character, it
is drawn in the ^X notation. Calling winch after adding a control
character (and moving to it, if necessary) does not return the control
character, but instead returns a character in the the ^-representation
of the control character.
All routines that return an integer return ERR upon failure and OK
(SVr4 specifies only "an integer value other than ERR") upon successful
completion, unless otherwise noted in the preceding routine descrip‐
Note that all but winsnstr may be macros.
These functions are described in the XSI Curses standard, Issue 4,
which adds const qualifiers to the arguments. The XSI Curses error
conditions EILSEQ and EILOVERFLOW associated with extended-level con‐
formance are not yet detected (this implementation does not yet support
XPG4 multi-byte characters).
