vfwprintf, vwprintf, vswprintf - wide-character formatted output of a stdarg argument list
#include <stdarg.h> #include <stdio.h> #include <wchar.h> int vwprintf(const wchar_t *format, va_list arg); int vfwprintf(FILE *stream, const wchar_t *format, va_list arg); int vswprintf(wchar_t *s, size_t n, const wchar_t *format, va_list arg);
The vwprintf(), vfwprintf() and vswprintf() functions are the same as wprintf(), fwprintf() and swprintf() 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 do not invoke the va_end macro. However, as these functions do invoke the va_arg macro, the value of ap after the return is indeterminate.

None.
Applications using these functions should call va_end(ap) afterwards to clean up.
None.
