VW_PRINTW(3XCURSES) X/Open Curses Library Functions VW_PRINTW(3XCURSES)

NAME

vw_printw - print formatted output in window

SYNOPSIS

cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib \
-R /usr/xpg4/lib -lcurses [ library... ]

c89 [ flag... ] file... -lcurses [ library... ]

#include <stdarg.h>
#include <curses.h>

int vw_printw(WINDOW *win, char *fmt, va_list varglist);

PARAMETERS

fmt
Is a printf() format string.


varglist
Is a pointer to a list of parameters.


win
Is a pointer to the window in which the string is to be
written.

DESCRIPTION

The vw_printw() function achieves the same effect as
wprintw(3XCURSES) using a variable argument list. The third argument
is a va_list, as defined in <stdarg.h>.

RETURN VALUES

Upon successful completion, vw_printw() returns OK. Otherwise, it
returns ERR.

ERRORS

No errors are defined.

USAGE

The vw_printw() function is preferred over vwprintw(3XCURSES). The
use of the vwprintw() and vw_printw() in the same file will not work,
due to the requirements to include <varargs.h> and <stdarg.h>, which
both contain definitions of va_list.
