/* Name: printw
 *
 * Synopsis:
 *       int printw(const char *fmt, ...);
 *       int wprintw(WINDOW *win, const char *fmt, ...);
 *       int mvprintw(int y, int x, const char *fmt, ...);
 *       int mvwprintw(WINDOW *win, int y, int x, const char *fmt,...);
 *       int vwprintw(WINDOW *win, const char *fmt, va_list varglist);
 *       int vw_printw(WINDOW *win, const char *fmt, va_list varglist);
 *
 * Description:
 *       The printw() functions add a formatted string to the window at
 *       the current or specified cursor position. The format strings are
 *       the same as used in the standard C library's printf(). (printw()
 *       can be used as a drop-in replacement for printf().)
 *
 * Return Value:
 *       All functions return the number of characters printed, or
 *       ERR on error.
 *
 * Portability                                X/Open    BSD    SYS V
 *       printw                                  Y       Y       Y
 *       wprintw                                 Y       Y       Y
