ICorDebugProcess::GetHelperThreadID Method
Gets the operating system (OS) thread ID of the debugger's internal helper thread.
HRESULT GetHelperThreadID (
[out] DWORD *pThreadID
);
Parameters
| Parameter | Description |
|---|---|
pThreadID |
[out] A pointer to the OS thread ID of the debugger's internal helper thread. |
Remarks
During managed and unmanaged debugging, it is the debugger's responsibility to ensure that the thread with the specified ID remains running if it hits a breakpoint placed by the debugger. A debugger may also wish to hide this thread from the user. If no helper thread exists in the process yet, the GetHelperThreadID method returns zero in *pThreadID.
You cannot cache the thread ID of the helper thread, because it may change over time. You must re-query the thread ID at every stopping event.
The thread ID of the debugger's helper thread will be correct on every unmanaged ICorDebugManagedCallback::CreateThread Method event, thus allowing a debugger to determine the thread ID of its helper thread and hide it from the user. A thread that is identified as a helper thread during an unmanaged ICorDebugManagedCallback::CreateThread Method event will never run managed user code.
