Constructor & Destructor Documentation

template<typename Range >

printf_arg_formatter< Range >::printf_arg_formatter ( internal::basic_buffer< char_type > &  buffer, format_specs &  spec, context_type &  ctx  )

inline

Constructs an argument formatter object. buffer* is a reference to the output buffer and spec contains format specifier information for standard argument types.

Definition at line 376 of file printf.h.
