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.

STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
printw, wprintw, mvprintw, mvwprintw, vw_printw, vwprintw: XCURSES4.2
Refer to the standards(5) reference page for more information about industry standards and associated tags.
DESCRIPTION
The printw, wprintw, mvprintw, and mvwprintw routines are analogous to printf family of routines (see printf(3)). In effect, the printw
routines output the string that would be output by printf as though waddstr were used on the given window.
The vw_printw routine is analogous to vprintf (see vprintf(3)) and performs the same operation as wprintw but uses a variable argument
list. The va_list type is a pointer to a list of arguments and is defined in <stdarg.h>.
The vwprintw routine is equivalent to vw_printw except that va_list is defined in <varargs.h>. The vw_printw routine is recommended for use
in new applications.
NOTES
The header file <curses.h> automatically includes the header file <stdio.h>.
RETURN VALUES
All routines return the integer ERR upon failure and OK upon successful completion.
