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 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.
