Function Documentation

fprintf() [1/2]

template<typename... T>

FMT_DEPRECATED auto fprintf	(	std::FILE *	f,
		basic_string_view< wchar_t >	fmt,
		const T &...	args )->int

fprintf() [2/2]

template<typename... T>

auto fprintf ( std::FILE * f, string_view fmt, const T &... args )->int

inline

Formats args according to specifications in fmt and writes the output to f.

Example:

fmt::fprintf(stderr, "Don't %s!", "panic");

make_printf_args()

template<typename Char = char, typename... T>

auto make_printf_args ( T &... args ) ->decltype(fmt::make_format_args< basic_printf_context< Char > >(args...))

inline

Constructs an format_arg_store object that contains references to arguments and can be implicitly converted to printf_args.

printf()

template<typename... T>

auto printf ( string_view fmt, const T &... args )->int

inline

Formats args according to specifications in fmt and writes the output to stdout.

Example:

fmt::printf("Elapsed time: %.2f seconds", 1.23);

sprintf() [1/2]

template<typename... T>

FMT_DEPRECATED auto sprintf	(	basic_string_view< wchar_t >	fmt,
		const T &...	args )->std::wstring

sprintf() [2/2]

template<typename... T>

auto sprintf ( string_view fmt, const T &... args )->std::string

inline

Formats args according to specifications in fmt and returns the result as as string.

Example:

std::string message = fmt::sprintf("The answer is %d", 42);

vfprintf()

template<typename Char>

auto vfprintf	(	std::FILE *	f,
		basic_string_view< Char >	fmt,
		typename vprintf_args< Char >::type	args )->int
