curs_printw(3X)                                                                              curs_printw(3X)



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 ef-fect, effect,
       fect, 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.

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       WITHDRAWN,  and is to be replaced by a function vw_printw using the 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  re-quires requires
       quires  including <varargs.h>, which cannot be used in the same file as <stdarg.h>.  This implementa-tion implementation
       tion uses <stdarg.h> for both, because that header is included in <curses.h>.
