TWaitResult - Enumerated value representing the method result.
WaitFor is a TWaitResult function used to block execution of the current thread until the current event receives a signal. WaitFor wraps calls to the overloaded WaitHandle.WaitOne methods from the FCL, and provides an enumerated value to represent the result of the operation.
Timeout indicates the optional number of milliseconds to wait for the signal on the waitable event handle. The value INFINITE indicates that the value in Timeout is not used when calling the overloaded WaitHandle.WaitOne method.
The return value for the method can contain one of the enumerated values defined in TWaitResult, with the following values and meanings:
