Detailed Description

A compound rate-limited socket layer.

A socket layer to which any number of

Member Function Documentation

◆ shutdown()

virtual int shutdown ( )
inlineoverridevirtual

Signals peers that we want to close the connections.

Only disallows further sends, does not affect reading from the socket.

Returns 0 on success, an error code otherwise. If it returns EGAIN, shutdown is not yet complete. Call shutdown again after the next write event.

Reimplemented from socket_layer.
