Function Documentation

void __declspec ( noreturn  )

inline

Cancels the currently executing task. This function can be called from within the body of a task to abort the task's execution and cause it to enter the canceled state. While it may be used in response to a cancellation request through a cancellation_token, you may also use it by itself, to initiate cancellation of the task that is currently executing.

It is not a supported scenario to call this function if you are not within the body of a task. Doing so will result in undefined behavior such as a crash or a hang in your application.
