Constructs a new cancellation_token_source . The source can be used to flag cancellation of some cancelable operation.

Cancels the token. Any task_group, structured_task_group, or task which utilizes the token will be canceled upon this call and throw an exception at the next interruption point.

Creates a cancellation_token_source which is canceled when the provided token is canceled.

Parameters

_Src A token whose cancellation will cause cancellation of the returned token source. Note that the returned token source can also be canceled independently of the source contained in this parameter.

Returns

A cancellation_token_source which is canceled when the token provided by the _Src parameter is canceled.

Creates a cancellation_token_source which is canceled when one of a series of tokens represented by an STL iterator pair is canceled.

Parameters

_Begin The STL iterator corresponding to the beginning of the range of tokens to listen for cancellation of.

_End The STL iterator corresponding to the ending of the range of tokens to listen for cancellation of.

Returns

A cancellation_token_source which is canceled when any of the tokens provided by the range described by the STL iterators contained in the _Begin and _End parameters is canceled.

Returns a cancellation token associated with this source. The returned token can be polled for cancellation or provide a callback if and when cancellation occurs.

Returns

A cancellation token associated with this source.
