       printw, wprintw, mvprintw, mvwprintw, vwprintw, vw_printw - print
       formatted output in curses windows

       #include <curses.h>

       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);

       The printw, wprintw, mvprintw and mvwprintw routines are	 analogous  to
       printf  [see printf(3)].	 In effect, the string that would be output by
       printf is output instead as though waddstr were used on the given  win‐

       The  vwprintw  and  wv_printw  routines	are  analogous to vprintf [see
       printf(3)] and perform a wprintw using a variable argument  list.   The
       third  argument	is a va_list, a pointer to a list of arguments, as de‐
       fined in <stdarg.h>.

       Routines that return an integer return ERR upon failure	and  OK	 (SVr4
       only  specifies "an integer value other than ERR") upon successful com‐

       X/Open defines no error conditions.  In this implementation,  an	 error
       may be returned if it cannot allocate enough memory for the buffer used
       to format the results.  It will return an error if the  window  pointer
       is null.

       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.

       The  XSI Curses standard, Issue 4 describes these functions.  The func‐
       tion vwprintw is marked TO BE WITHDRAWN, and is to  be  replaced	 by  a
       function	 vw_printw  using  the	<stdarg.h> interface.  The Single Unix
       Specification, Version 2 states that vw_printw	is  preferred  to  vw‐
       printw since the latter requires including <varargs.h>, which cannot be
       used  in	 the  same  file  as  <stdarg.h>.   This  implementation  uses
       <stdarg.h> for both, because that header is included in <curses.h>.
