IHostSyncManager::CreateMonitorEvent Method

Creates a monitored auto-reset event object.

HRESULT CreateMonitorEvent (
    [in]  SIZE_T cookie,
    [out] IHostAutoEvent **ppEvent
);

Parameters

  • cookie
    [in] A cookie to associate with the event object.
  • ppEvent
    [out] A pointer to the address of an IHostAutoEvent Interface instance, or null if the event object could not be created.

Return Value

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 method.
