VFWSCANF(3P) POSIX Programmer's Manual VFWSCANF(3P)
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.
vfwscanf, vswscanf, vwscanf — wide-character formatted input of a
stdarg argument list
#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);
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.
Refer to fwscanf(3p).
Refer to fwscanf(3p).
The following sections are informative.
None.
Applications using these functions should call va_end(ap) afterwards
to clean up.
None.
None.
