ins_wstr, ins_nwstr, wins_wstr, wins_nwstr, mvins_wstr,
mvins_nwstr, mvwins_wstr, mvwins_nwstr - insert a wide-character
string into a curses window
#include <curses.h>
int ins_wstr(const wchar_t *wstr);
int ins_nwstr(const wchar_t *wstr, int n);
int wins_wstr(WINDOW *win, const wchar_t *wstr);
int wins_nwstr(WINDOW *win, const wchar_t *wstr, int n);
int mvins_wstr(int y, int x, const wchar_t *wstr);
int mvins_nwstr(int y, int x, const wchar_t *wstr, int n);
int mvwins_wstr(WINDOW *win, int y, int x, const wchar_t *wstr);
int mvwins_nwstr(WINDOW *win, int y, int x, const wchar_t *wstr, int n);
These routines insert a wchar_t character string (as many charac‐
ters as will fit on the line) before the character under the cur‐
sor. All characters to the right of the cursor are shifted right,
with the possibility of the rightmost characters on the line being
lost. No wrapping is performed. 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 wchar_t characters. If n is less than 1, the entire string is
inserted.
If a character in wstr is a tab, newline, carriage return or back‐
space, 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 wstr is another
control character, it is drawn in the ^X notation. Calling
win_wch after adding a control character (and moving to it, if
necessary) does not return the control character, but instead re‐
turns a character in the ^-representation of the control charac‐
ter.
Note that all but wins_nwstr may be macros.
If the first character in the string is a nonspacing character,
these functions will fail. XSI does not define what will happen
if a nonspacing character follows a control character.
Upon successful completion, these functions return OK. Otherwise,
they return ERR.
Functions with a “mv” prefix first perform a cursor movement using
wmove, and return an error if the position is outside the window,
or if the window pointer is null.
