Base Classes

Name	Description
`std::basic_ostream<CHAR_TYPE, CHAR_TRAITS>`	Template class basic_ostream.

Types

Name	Description
`sentry`	Performs setup work for output streams.

Type Aliases

Name	Description
`allocator_type`	Allocator type used by this stream.
`char_type`	Character type manipulated by this stream.
`int_type`	Integer type returned by stream operations.
`off_type`	Offset type used by the character traits.
`pos_type`	Position type used by the character traits.
`streambuf_type`	Stream buffer type wrapped by this stream's sync buffer.
`syncbuf_type`	Synchronized stream buffer type used by this output stream.
`traits_type`	Character traits type used by this stream.

Member Functions

Name	Description
`basic_osyncstream` [constructor]	Constructors
`operator=`	Transfer the associated output to the wrapped stream buffer then assign to this object the value of the specified `original`, and return a reference providing modifiable access to this object. The contents of `original` are move-assigned to this object. `original.get_wrapped() == nullptr` after the call.
`emit`	Atomically transfer any characters buffered by this object to the wrapped stream buffer, so that it appears in the output stream as a contiguous sequence of characters. If an error occurs, set the `badbit` of the `rdstate` to `true`.
`get_allocator`	Return the allocator used to supply memory.
`get_wrapped`	Return the wrapped buffer.
`rdbuf`	Return an address providing modifiable access to the `basic_syncbuf` object that is internally used by this stream object to buffer unformatted characters.
