    [in]  SIZE_T cookie,  
    [out] IHostAutoEvent **ppEvent  


[in] A cookie to associate with the auto-reset event.

[out] A pointer to the address of an IHostAutoEvent instance, or null if the event object could not be created.

S_OKCreateRWLockWriterEvent returned successfully.
HOST_E_CLRNOTAVAILABLEThe common language runtime (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_TIMEOUTThe call timed out.
HOST_E_NOT_OWNERThe caller does not own the lock.
HOST_E_ABANDONEDAn event was canceled while a blocked thread or fiber was waiting on it.
E_FAILAn 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.
E_OUTOFMEMORYNot enough memory was available to create the requested event object.

The CLR calls the CreateRWLockWriterEvent method to get a reference to an IHostAutoEvent instance to use in its implementation of a writer lock. The host can use the specified cookie to determine which tasks are waiting on the lock by calling the iteration methods of the ICLRSyncManager interface.
