Reads formatted text from wide-character oriented stdin.

This function is compatible with the following targets:

ANSI

BeOS

EMB/RTOS

Mac OS

Palm OS

Win32

#include <wchar.h>

int vwscanf(const wchar_t * format, va_list arg);

Parameters for this function are:

s	wchar_t*	The string being read
format	wchar_t*	The format string
....		Variable arguments

The vwscantf() function works identically to the wscanf() function. Instead of the variable list of arguments that can be passed to wscanf(), vwscanf() accepts its arguments in the array arg of type va_list, which must have been initialized by the va_start() macro (and possibly subsequent va_arg calls) from the stdarg.h header file. The vwscanf() function does not invoke the va_end macro.

Refer to the "wscanf" function for details of the format string.

The vwscanf() function returns the number of items assigned, which can be fewer than provided for in the case of an early matching failure. If an input failure occurs before any conversion, vwscanf() returns EOF.
