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

13       vfwscanf, vswscanf, vwscanf  —  wide-character  formatted  input  of  a
14       stdarg argument list
15

SYNOPSIS

17       #include <stdarg.h>
18       #include <stdio.h>
19       #include <wchar.h>
20
21       int vfwscanf(FILE *restrict stream, const wchar_t *restrict format,
22           va_list arg);
23       int vswscanf(const wchar_t *restrict ws, const wchar_t *restrict format,
24           va_list arg);
25       int vwscanf(const wchar_t *restrict format, va_list arg);
26

DESCRIPTION

28       The  functionality described on this reference page is aligned with the
29       ISO C standard. Any conflict between the  requirements  described  here
30       and  the  ISO C  standard is unintentional. This volume of POSIX.1‐2008
31       defers to the ISO C standard.
32
33       The vfwscanf(), vswscanf(), and vwscanf() functions shall be equivalent
34       to  the  fwscanf(),  swscanf(),  and  wscanf() functions, respectively,
35       except that instead of being called with a  variable  number  of  argu‐
36       ments,  they  are  called  with  an  argument  list  as  defined in the
37       <stdarg.h> header. These functions shall not invoke the  va_end  macro.
38       As  these  functions invoke the va_arg macro, the value of ap after the
39       return is unspecified.

EXAMPLES

50       None.
51

APPLICATION USAGE

53       Applications using these functions should call va_end(ap) afterwards to
54       clean up.
