Name

vw_scanw– convert formatted input from a 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_scanw(WINDOW *win, char *fmt, va_list varglist);

Parameters

fmt

Is a scanf() format string.

varglist

Is a pointer to a list of parameters.

win

Is a pointer to the window in which the character is to be read.

Description

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

Return Values

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

Errors

No errors are defined.

Usage

The vw_scanw() function is preferred over vwscanw(3XCURSES). The use of the vwscanw() and vw_scanw() 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.
