std::basic_syncbuf<CharT,Traits,Allocator>::emit

bool emit();

Atomically transmits all pending output to the wrapped stream.

All emit() calls transferring characters to the same wrapped stream buffer object appear to execute in a total order, where each emit() call synchronizes-with subsequent emit() calls in that total order, even if these calls are made through difference instances of std::basic_syncbuf/std::basic_osyncstream

If a call had been made to sync since the last call to emit(), then also flushes the wrapped stream by calling pubsync()

Parameters

(none)

Return value

true if all of the following is true:

• there is a wrapped stream (the wrapped streambuf pointer is not null)
• all characters from the temporary storage were successfully sent into the wrapped stream
• the call to pubsync(), if requested, also completed successfully.

Returns false otherwise.

Notes

Normally called by the destructor or move assignment of the owning std::basic_osyncstream, or by std::basic_osyncstream::emit
