PsGetThreadId function (ntddk.h)

  • Article

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.
