cancellation_token::none Method

Returns a cancellation token which can never be subject to cancellation.

static cancellation_token none();

Return Value

A cancellation token that cannot be canceled.

Remarks

The none() token can be explicitly assigned to a task_group or structured_task_group to block the implicit cancellation propagation from a parent construct. In conjuction with run_with_cancellation_token, it can also be used to safe guard parallel algorithms from unintended cancellation from above.

Requirements

Header: ppl.h

Namespace: concurrency
