Here is the caller graph for this function:

bin()

IntFormatSpec<int, TypeSpec<'b'> > fmt::bin

(

int

value

)

Returns an integer format specifier to format the value in base 2.

format() [1/3]

template<typename Char , typename ArgFormatter , typename T >

void fmt::format	(	BasicFormatter< Char, ArgFormatter > &	f,
		const Char *&	format_str,
		const T &	value
	)

Definition at line 91 of file ostream.h.

format() [2/3]

std::string fmt::format ( CStringRef  format_str, ArgList  args  )

format_system_error()

FMT_FUNC void fmt::format_system_error	(	fmt::Writer &	out,
		int	error_code,

\rst Formats an error returned by an operating system or a language runtime, for example a file opening error, and writes it to out in the following form:

.. parsed-literal:: <message>*: *<system-message>*

where *<message>* is the passed message and *<system-message>* is the system message corresponding to the error code. error_code* is a system error code as given by errno. If error_code is not a valid error code such as -1, the system message may look like "Unknown error -1" and is platform-dependent. \endrst
