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.
