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

PROLOG         top

       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         top

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

SYNOPSIS         top

       #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         top

       The functionality described on this reference page is aligned with
       the ISO C standard. Any conflict between the requirements described
       here and the ISO C standard is unintentional. This volume of
       POSIX.1‐2008 defers to the ISO C standard.

       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 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         top

       Refer to fwscanf(3p).

ERRORS         top

       Refer to fwscanf(3p).

       The following sections are informative.

EXAMPLES         top

       None.

APPLICATION USAGE         top

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

RATIONALE         top

       None.

FUTURE DIRECTIONS         top

       None.
