NAME

6       vfwscanf,  vswscanf,  vwscanf  -  wide-character  formatted  input of a
7       stdarg argument list

SYNOPSIS

10       #include <stdarg.h>
11       #include <stdio.h>
12       #include <wchar.h>
13
14       int vfwscanf(FILE *restrict stream, const wchar_t *restrict format,
15              va_list arg);
16       int vswscanf(const wchar_t *restrict ws, const wchar_t  *restrict  for‐
17       mat,
18              va_list arg);
19       int vwscanf(const wchar_t *restrict format, va_list arg);

DESCRIPTION

23       The vfwscanf(), vswscanf(), and vwscanf() functions shall be equivalent
24       to the fwscanf(),  swscanf(),  and  wscanf()  functions,  respectively,
25       except  that  instead  of  being called with a variable number of argu‐
26       ments, they are  called  with  an  argument  list  as  defined  in  the
27       <stdarg.h>  header.  These functions shall not invoke the va_end macro.
28       As these functions invoke the va_arg macro, the value of ap  after  the
29       return is unspecified.
