IHostGCManager::SuspensionStarting Method

Notifies the host that the common language runtime (CLR) is suspending execution of tasks, to perform a garbage collection.


HRESULT SuspensionStarting ();  

Return Value

HRESULT Description
S_OK SuspensionStarting 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.


The CLR calls SuspensionStarting to inform the host that garbage collection is occurring.


Do not reschedule this task. The host must reschedule a task when ThreadIsBlockingForSuspension is called.
