VFWSCANF(3P)               POSIX Programmer's Manual              VFWSCANF(3P)

PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the  corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.
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 for-
       mat,
              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  argu-
       ments,  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.
