printw(3NCURSES)                                              printw(3NCURSES)

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  win-
       dow.

       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>.

RETURN VALUE
       Routines that return an integer return ERR upon failure  and  OK  (SVr4
       only  specifies "an integer value other than ERR") upon successful com-
       pletion.

       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.

PORTABILITY
       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       tion vwprintw is marked TO BE WITHDRAWN, and is to  be  replaced  by  a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>.
