ICLRSyncManager::GetMonitorOwner Method
Gets the IHostTask instance that owns the monitor identified by the specified cookie.
HRESULT GetMonitorOwner (
[in] SIZE_T cookie,
[out] IHostTask *ppOwnerHostTask
);
Parameters
cookie
[in] The cookie associated with the monitor.ppOwnerHostTask
[out] A pointer to the IHostTask that currently owns the monitor, or null if no task has ownership.
Return Value
HRESULT |
Description |
|---|---|
S_OK |
GetMonitorOwner 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. |
Remarks
The host typically calls GetMonitorOwner as part of a deadlock-detection mechanism. The cookie is associated with a monitor when it is created by using a call to IHostSyncManager::CreateMonitorEvent.

|---|
A call to release the event underlying the monitor might block—but will not deadlock—if a call to this method is currently in effect on the cookie associated with that monitor. Other tasks might also block if they attempt to acquire this monitor. |
GetMonitorOwner always returns immediately and can be called any time after a call to CreateMonitorEvent. The host does not need to wait until a task is waiting on the event.
