How this entity was disambiguated
This entity first appeared as the object of triple T8288313 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: WaitForSingleObject Context triple: [Kernel32, exportsFunction, WaitForSingleObject]
-
A.
EventWaitHandle
EventWaitHandle is a .NET synchronization primitive that allows threads or processes to signal and wait for events, coordinating execution flow in concurrent applications.
-
B.
RegisteredWaitHandle
RegisteredWaitHandle is a .NET threading class that represents a handle to a registered wait operation, allowing callbacks to be invoked when a WaitHandle is signaled or a timeout occurs.
-
C.
AutoResetEvent
AutoResetEvent is a synchronization primitive in .NET used to manage signaling between threads by automatically resetting its state after releasing a single waiting thread.
-
D.
System.Threading
System.Threading is a .NET namespace that provides types and APIs for working with threads, tasks, synchronization, and concurrent programming.
-
E.
ManualResetEvent
ManualResetEvent is a .NET synchronization primitive that allows threads to wait until a signal is set and remains signaled until it is manually reset.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: WaitForSingleObject Description of subject: WaitForSingleObject is a Windows API synchronization function that blocks a thread until a specified object is signaled or a timeout interval elapses.
