This routine returns the unique identifier (ID) of a given thread.
Syntax
HANDLE PsGetThreadId(
[in] PETHREAD Thread
);
Parameters
[in] Thread
A pointer to an executive thread object structure (ETHREAD).
Return value
Returns a HANDLE that is the unique ID of the caller-supplied thread.
Remarks
A driver might call PsGetThreadId for several reasons:
Thread Identification: The thread ID returned by PsGetThreadId is unique system-wide, not just within a single process.
Debugging and Logging: Thread IDs are often used in debugging and logging to trace the execution of the program.
Thread ID is not unique for a boot session. After a thread has terminated its ID may be reused.
