class function CheckTerminated: Boolean; static;
static bool __fastcall CheckTerminated();
Indicates whether the thread has been asked to terminate.
Use CheckTerminated to check whether the Terminated flag has been set on the current thread.
This class function returns the same value as the Terminated property, only that you can call CheckTerminated from outside the thread class. From within the thread class, use Terminated instead, as its performance is slightly better.
