  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
	mvprintw				Y	Y	Y
	mvwprintw				Y	Y	Y
	vwprintw				Y	-      4.0
