PROLOG

6       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
7       implementation of this interface may differ (consult the  corresponding
8       Linux  manual page for details of Linux behavior), or the interface may
9       not be implemented on Linux.

NAME

12       vfwscanf, vswscanf, vwscanf  -  wide-character  formatted  input  of  a
13       stdarg argument list
14

SYNOPSIS

16       #include <stdarg.h>
17       #include <stdio.h>
18       #include <wchar.h>
19
20       int vfwscanf(FILE *restrict stream, const wchar_t *restrict format,
21              va_list arg);
22       int  vswscanf(const  wchar_t *restrict ws, const wchar_t *restrict for‐
23       mat,
24              va_list arg);
25       int vwscanf(const wchar_t *restrict format, va_list arg);

DESCRIPTION

29       The vfwscanf(), vswscanf(), and vwscanf() functions shall be equivalent
30       to  the  fwscanf(),  swscanf(),  and  wscanf() functions, respectively,
31       except that instead of being called with a  variable  number  of  argu‐
32       ments,  they  are  called  with  an  argument  list  as  defined in the
33       <stdarg.h> header. These functions shall not invoke the  va_end  macro.
34       As  these  functions invoke the va_arg macro, the value of ap after the
35       return is unspecified.
36

RETURN VALUE

38       Refer to fwscanf().
39

ERRORS

41       Refer to fwscanf().

EXAMPLES

46       None.
47

APPLICATION USAGE

49       Applications using these functions should call va_end(  ap)  afterwards
50       to clean up.
51

RATIONALE

53       None.

FUTURE DIRECTIONS

56       None.
