vfwprintf, vswprintf, vwprintf − wide-character formatted output of a stdarg argument list
#include
<stdarg.h>
#include <stdio.h>
#include <wchar.h>
int
vfwprintf(FILE *restrict stream, const wchar_t
*restrict format,
va_list arg);
int vswprintf(wchar_t *restrict ws, size_t
n,
const wchar_t *restrict format, va_list
arg);
int vwprintf(const wchar_t *restrict format,
va_list arg);
The vfwprintf(), vswprintf(), and vwprintf() functions shall be equivalent to fwprintf(), swprintf(), and wprintf() respectively, except that instead of being called with a variable number of arguments, they are called with an argument list as defined by <stdarg.h>.
These functions shall not invoke the va_end macro. However, as these functions do invoke the va_arg macro, the value of ap after the return is unspecified.
Refer to fwprintf() .
Refer to fwprintf() .
The following sections are informative.
None.
Applications using these functions should call va_end(ap) afterwards to clean up.
None.
None.
