* int addnstr(const char *str, int n);
|
|
* int waddstr(WINDOW *win, const char *str);

|
|
* int mvwaddnwstr(WINDOW *win, int y, int x, const wchar_t *wstr, int n);
|
|
*
|
|
* Description:
|
|
* These routines write all the characters of the null-terminated
|
|
* string str or wide-character string wstr to the given window.
|
|
* The functionality is similar to calling waddch() once for each
|
|
* character in the string; except that, when PDCurses is built
|
|
* with wide-character support enabled, the narrow-character
|
|
* functions treat the string as a multibyte string in the current
|
|
* locale, and convert it. The routines with n as the last
|
|
* argument write at most n characters; if n is negative, then the
|
|
* entire string will be added.
|
|
*
|
|
* Return Value:
|
|
* All functions return OK or ERR.
|
|
*
|
|
* Portability X/Open BSD SYS V
