basic_deadline_timer::cancel (2 of 2 overloads)

Cancel any asynchronous operations that are waiting on the timer.

std::size_t cancel(
    boost::system::error_code & ec);

This function forces the completion of any pending asynchronous wait operations against the timer. The handler for each cancelled operation will be invoked with the boost::asio::error::operation_aborted error code.

Cancelling the timer does not change the expiry time.

Parameters

ec

Set to indicate what error occurred, if any.

Return Value

The number of asynchronous operations that were cancelled.
