Return Value

HRESULT Description
S_OK SetTaskIdentifier returned successfully.
HOST_E_CLRNOTAVAILABLE 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.
HOST_E_TIMEOUT The call timed out.
HOST_E_NOT_OWNER The caller does not own the lock.
HOST_E_ABANDONED An event was canceled while a blocked thread or fiber was waiting on it.
E_FAIL 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.
