Cancel all asynchronous operations associated with the socket.

However, we note from the linked documentation: * It will only cancel asynchronous operations that were initiated in the current thread. * It can appear to complete without error, but the request to cancel the unfinished operations may be silently ignored by the operating system. – Sam Liddicott Mar 02 '16 at 14:26
@SamLiddicott Please note that this applies only to CancelIo (Windows) , if enabled by BOOST_ASIO_ENABLE_CANCELIO – LangerJan Mar 09 '16 at 14:28
@SamMiller That is such a relief! Thanks for clarifying! – Sam Liddicott Mar 09 '16 at 18:26
