	field	member functions	description
Formatting	format flags	`flags` `setf` `unsetf`	A set of internal flags that affect how certain input/output operations are interpreted or generated. See member type `fmtflags`.
	field width	`width`	Width of the next formatted element to insert.
	display precision	`precision`	Decimal precision for the next floating-point value inserted.
	locale	`getloc` `imbue`	The `locale` object used by the function for formatted input/output operations affected by localization properties.
	fill character	`fill`	Character to pad a formatted field up to the field width (`width`).
State	error state	`rdstate` `setstate` `clear`	The current error state of the stream. Individual values may be obtained by calling `good`, `eof`, `fail` and `bad`. See member type `iostate`.
State	exception mask	`exceptions`	The state flags for which a failure exception is thrown. See member type `iostate`.
Other	callback stack	`register_callback`	Stack of pointers to functions that are called when certain events occur.
	extensible arrays	`iword` `pword` `xalloc`	Internal arrays to store objects of type `long` and `void*`.
	tied stream	`tie`	Pointer to output stream that is flushed before each i/o operation on this stream.
	stream buffer	`rdbuf`	Pointer to the associated `basic_streambuf` object, which is charge of all input/output operations.
	character count	`gcount`	Count of characters read by last unformatted input operation (input streams only).

member type	definition	notes
`char_type`	The first template parameter (`charT`)
`traits_type`	The second template parameter (`traits`)	defaults to: `char_traits<charT>`
`int_type`	`traits_type::int_type`
`pos_type`	`traits_type::pos_type`	generally, the same as `streampos`
`off_type`	`traits_type::off_type`	generally, the same as `streamoff`
