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 (con-
       sult 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 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() func-
       tions, 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.
