Synopsis

void
cancel();

Description

The Client immediately enters the stopped state. All operations still pending on the current run will complete with boost::asio::error::operation_aborted. Communication operations initiated after this call also complete with boost::asio::error::operation_aborted until async_run is called again.

Attention

This function has terminal effects and will close the Client. The Client cannot be used for communication before calling async_run again.
