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 s, size_t n,
const wchar_t *restrict format, va_list arg);
int vwprintf(const wchar_t *restrict 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.
Refer to fwprintf(3C).
Refer to fwprintf(3C).
Applications using these functions should call va_end(ap) afterwards to clean up.
See attributes(5) for descriptions of the following attributes:
| |||||||||
fwprintf(3C), setlocale(3C), attributes(5), standards(5)
The vwprintf(), vfwprintf(), and vswprintf() functions can be used safely in multithreaded applications, as long as setlocale(3C) is not being called to change the locale.
