IHostGCManager::ThreadIsBlockingForSuspension Method
Notifies the host that the thread from which the method call was made is about to block for a garbage collection.
HRESULT ThreadIsBlockingForSuspension ();
Return Value
HRESULT |
Description |
---|---|
S_OK |
ThreadIsBlockingForSuspension 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. |
Remarks
The CLR typically calls the ThreadIsBlockForSuspension method in preparation for a garbage collection, to give the host an opportunity to reschedule the thread for unmanaged tasks.
Important Note: |
---|
The host can reschedule tasks only after a call to ThreadIsBlockingForSuspension. After the runtime calls SuspensionStarting, the host must not reschedule a task. |
