WaitWriteable()

virtual bool engine::io::WritableBase::WaitWriteable ( Deadline deadline )

nodiscardpure virtual

Suspends current task until the data is available.

Implemented in engine::io::PipeWriter, engine::io::Socket, and engine::io::TlsWrapper.

WriteAll() [1/2]

Note

Can return less than len if stream is closed by peer.

Implemented in engine::io::PipeWriter, engine::io::Socket, and engine::io::TlsWrapper.
