HRESULT SetTaskIdentifier (
    [in] DWORD Asked


[in] The unique identifier for the common language runtime to associate with the task represented by the current ICLRTask instance.




SetTaskIdentifier returned successfully.


The CLR has not been loaded into a process, or the CLR is in a state in which it cannot run managed code or process the call successfully.


The call timed out.


The caller does not own the lock.


An event was canceled while a blocked thread or fiber was waiting on it.


An unknown catastrophic failure occurred. When a method returns E_FAIL, the CLR is no longer usable within the process. Subsequent calls to hosting methods return HOST_E_CLRNOTAVAILABLE.

The host can associate an identifier with a task to help integrate the CLR and the host in a debugging environment. The identifier has no meaning for the CLR. The CLR passes it along to a debugger application. The debugger can use this identifier to associate a CLR call stack with a host call stack, and enable their respective trace information to be unified when viewed in the debugger's user interface.
