NAME

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

SYNOPSIS

       #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);

DESCRIPTION

       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 window.

       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 defined in <stdarg.h>.

RETURN VALUE

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

       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.

PORTABILITY

       The XSI Curses standard, Issue 4 describes these  functions.   The  function  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       marked TO BE WITHDRAWN, and is to be replaced by a function vw_printw using the 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  vwprintw  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>.
