HRESULT |
Description |
|---|---|
S_OK |
CreateMonitorEvent returned successfully. |
HOST_E_CLRNOTAVAILABLE |
The 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_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. |
E_OUTOFMEMORY |
Not enough memory was available to create the requested event object. |
Remarks
CreateMonitorEvent returns an IHostAutoEvent that the CLR uses in its implementation of the managed System.Threading..::.Monitor type. This method mirrors the Win32 CreateEvent function, with a value of false specified for the bManualReset parameter.
The host can use the cookie to determine which task is waiting on the monitor by calling the ICLRSyncManager::GetMonitorOwner method.
