- insert wchar_t string before character under the cursor in a curses window
cc [ flag ... ] file ... -lcurses [ library .. ] #include <curses.h> int inswstr(wchar_t *wstr);
int insnwstr(wchar_t *wstr, int n);
int winswstr(WINDOW *win, wchar_t *wstr);
int winsnwstr(WINDOW *win, wchar_t *wstr, int n);
int mvinswstr(int y, int x, wchar_t *wstr);
int mvinsnwstr(int y, int x, wchar_t *wstr, int n);
int mvwinswstr(WINDOW *win, int y, int x, wchar_t *wstr);
int mvwinsnwstr(WINDOW *win, int y, int x, wchar_t *wstr, int n);
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 cursor position does not change (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 entire string is inserted.
If a character in wstr is a tab, newline, carriage return, or backspace, the cursor is moved appropriately within the window. A newline also does a clrtoeol(3CURSES) 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 winwch(3CURSES) 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.
All routines return the integer ERR upon failure and an integer value other than ERR upon successful completion.

Note that all but winsnwstr() may be macros.
