These routines insert a wchar_t character string (as many wchar_t characters as will fit on the line) before the character under the cursor. All characters to the right of the cursor are moved to the right, with the possibility of the rightmost characters on the line being lost. The routines do not change the cursor position after moving to y, x, if specified. (This does not imply use of the hardware insert character feature.)
The four routines with n as the last argument insert at most n wchar_t characters. If n<=0, then the routines insert the entire string.
If a character in
wstr
is a tab, newline,
carriage return, or backspace, the cursor is moved appropriately within the
window. A newline also results in
clrtoeol
before moving.
Tabs are considered to be at every eighth column. If a character in
wstr
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 the representation of the
control character.
The header file <curses.h> automatically includes the header file <stdio.h>.
Note that all but winsnwstr may be macros.
The routines described on this reference page are among the MNLS Curses
functions that are not included in the X/Open Curses CAE specification. MNLS
routines are supported only for backward compatibility reasons. Compaq
recommends the use of the
*ins_wstr
and
*ins_nwstr
functions in new applications (see
curs_ins_wstr(3)).
All routines return the integer
ERR
upon
failure and an integer value other than
ERR
upon
successful completion.
