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(3S)]. 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(3S)] 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.
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marked TO BE WITHDRAWN, and is to be replaced by a function vw_printw using the 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>.
