VSWSCANF(3) Library Functions Manual VSWSCANF(3)

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

[CX] 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 IEEE Std 1003.1-2001 (“POSIX.1”) defers to the ISO C standard.

The vfwscanf (), vswscanf (), and vwscanf () functions shall be equivalent to the fwscanf(3), swscanf(3), and wscanf(3) 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.
