NAME
vfwscanf, vswscanf, vwscanf - wide-character formatted input of a
stdarg argument list
SYNOPSIS
#include <stdarg.h>
#include <stdio.h>
#include <wchar.h>
int vfwscanf(FILE *restrict stream, const wchar_t *restrict
format,
va_list arg);
int vswscanf(const wchar_t *restrict ws, const wchar_t
*restrict format,
va_list arg);
int vwscanf(const wchar_t *restrict format, va_list
arg);
DESCRIPTION
The vfwscanf(), vswscanf(), and vwscanf() functions
shall be equivalent to the fwscanf(), swscanf(), and wscanf()
functions, respectively, except that instead of being called with
a variable number
of arguments, they are called with an argument list as defined in
the <stdarg.h> header. These functions shall not invoke the
va_end macro. As these
functions invoke the va_arg macro, the value of ap after
the return is unspecified.
RETURN VALUE
Refer to fwscanf() .
ERRORS
Refer to fwscanf() .
The following sections are informative.
EXAMPLES
None.
APPLICATION USAGE
Applications using these functions should call va_end( ap)
afterwards to clean up.
RATIONALE
None.
FUTURE DIRECTIONS
None.
