)
template<typename Char >
void fmt::arg ( WStringRef  ,
const internal::NamedArg< Char > &   
)
IntFormatSpec<int, TypeSpec<'b'> > fmt::bin ( int  value)

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

Here is the caller graph for this function:

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

)

Definition at line 91 of file ostream.h.

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

Formats arguments and returns the result as a string.

Example**::

std::string message = format("The answer is {}", 42);

Definition at line 3141 of file format.h.

std::wstring fmt::format ( WCStringRef  format_str,
ArgList  args

inline

Definition at line 3258 of file format.h.

FMT_FUNC void fmt::format_system_error ( fmt::Writer out,
int  error_code,
fmt::StringRef  message 
)

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.

Definition at line 388 of file format.cc.

Here is the caller graph for this function:

FMT_API int fmt::fprintf ( std::ostream &  os,
CStringRef  format_str,
ArgList  args 
)

Prints formatted data to the stream os.

Example**::

fprintf(cerr, "Don't %s!", "panic");

Definition at line 56 of file ostream.cc.

Here is the caller graph for this function:

FMT_FUNC int fmt::fprintf ( std::FILE *  f,
CStringRef  format,
ArgList  args 
)

Prints formatted data to the file f.

Example**::

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

Definition at line 507 of file format.cc.

long fmt::getpagesize ( )

Definition at line 245 of file posix.cc.

Here is the caller graph for this function:

IntFormatSpec<int, TypeSpec<'x'> > fmt::hex ( int  value)

Returns an integer format specifier to format the value in base 16 using lower-case letters for the digits above 9.

Here is the caller graph for this function:

IntFormatSpec<int, TypeSpec<'X'> > fmt::hexu ( int  value)

Returns an integer formatter format specifier to format in base 16 using upper-case letters for the digits above 9.

Here is the caller graph for this function:

IntFormatSpec<int, TypeSpec<'o'> > fmt::oct ( int  value)

Returns an integer format specifier to format the value in base 8.

Here is the caller graph for this function:

template<char TYPE_CODE, typename Char >
IntFormatSpec<int, AlignTypeSpec<TYPE_CODE>, Char> fmt::pad ( int  value,
unsigned  width,
Char  fill = ' ' 
)

Returns an integer format specifier to pad the formatted argument with the fill character to the specified width using the default (right) numeric alignment.

Example**::

MemoryWriter out; out << pad(hex(0xcafe), 8, '0'); out.str() == "0000cafe"

Here is the caller graph for this function:

template<typename Char >
StrFormatSpec<Char> fmt::pad ( const Char *  str,
unsigned  width,
Char  fill = ' ' 
)
inline

Returns a string formatter that pads the formatted argument with the fill character to the specified width using the default (left) string alignment.
