GetOriginatorThreadId Method

Retrieves the Id of the thread that initiated the operation.

Syntax

public int getOriginatorThreadId();

Remarks

This method can be called within events fired for filesystem operations to retrieve the Id of the thread that initiated the operation. If the query fails, this method returns 0.

Please note that thread Ids are not unique, and may be reused by different threads over time.

Note: This method can only be called within events, and must be called in the same thread that the event was originally fired on. However, it must not be called within events that work with opened files since such events can be initiated by system components (e.g., the cache manager, memory manager, etc.). If applications need the information this method returns during such events, they may do the following:

1. Call this method within the CreateFile or OpenFile event.
2. Store the information somewhere, and store a reference to it in the event's HandleContext parameter.
3. In a later event, access the information via the reference stored in HandleContext.

Note: Renaming and deletion of files is performed after the file is opened. Thus, access checks should be performed during file opening as described above.

Note: This method cannot be used from CleanupContext event handlers.
