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().)

   The duplication between vwprintw() and vw_printw() is for historic
   reasons. In PDCurses, they're the same.

### Return Value

   All functions return the number of characters printed, or ERR on
   error.
